| Term | Definition |
|---|---|
| If you jog for 1 h and travel 10 k/m, 10 km/h describes your what? | Average Speed |
| ____________ is a speed in a certain direction. | Velocity |
| An objects speed is a measure of... | How fast the object is moving |
| A car travels the distance of 210 mi in exactly 4 hours. The driver calculates he traveled 52.5 mi/h . What term most nearly describes his calculations? | Average Speed |
| Which of the Quantities below represents a velocity? 25 M/S, 10 Km/Min, 15 Mi/H eastward, 3 Mi/H. | 15 Mi/H Eastward |
| Which of the following is NOT accelerating? A ball being juggled, a woman walking at 2.5 M/S along a strait road, a satellite circling earth, a breaking cyclist | A woman walking as 2.5 M/S along a strait road |
| At the end of a game, a basketball player on the winning team throws the basketball strait up as high as he can throw it. At the top of its path, the basketballs velocity is... | 0 M/S (Balanced) |
| Which one of the following is NOT caused by a net force? Changing a bicycles speed while it is moving in a strait line, changing a bicycles direction while it is moving at a constant speed, keeping a bicycle going in a strait line at constant speed | Keeping a bicycle going in a strait line at constant speed. |
| 9. A book is sitting still on you desk. How would you describe the book? | There are balanced forces acting on the book |
| State whether 30 M/S westward represents a speed, velocity, or both | Both |
| Why is identifying the reference frame important in describing motion? | A “Reference Frame” is very important in describing motion because it gives or provides a form of measurement |
| What is the difference between distance and displacement? | The difference between distance and displacement is distance is the total amount traveled, while displacement is the exact distance between the beginning and the end. |
| What is Uniform Circular Motion? | Uniform Circular Motion is when an object has a constant speed and a constant change in motion |
| How are friction and air resistance alike? How are they different? | They are alike in that they are both forces that most of the time work against the movement of an object, but they are different in the fact that friction is more rudimentary and commonly seen then air resistance. |
| How do static friction and kinetic friction differ from each other? | Static friction is an object with charged up energy that requires more force to get going then an object under going kinetic friction which is an object in motion that is using its energy. |
| Calculate the speed for a car the went a distance of 125 kilometers in 2 hours time. | 62.5 K/H |
| A baseball is thrown a distance of 20 meters. What is its speed if it takes 0.5 seconds to cover the distance? | 40 M/S |
| How much time does it take for a bird flying at a speed of 45 kilometers per hour to travel a distance of 1,800 kilometers? | 40 Hours |
| A comet is cruising through the solar system at a speed of 50,000 kilometers per hour for 4 hours time. What is the total distance traveled by the comet during this time? | 200,000 Km |
| If Steve throws the football 50 meters in 3 seconds, what is the average speed (velocity) of the football? | 16.6 M/S |
| If it takes Ashley 3 seconds to run from the batters box to first base at an average speed (velocity) of 6.5 meters per second, what is the distance she covers in that time? | 19.5 meters |
| Bart ran 5000 meters from the cops and an average speed (velocity) of 6 meters/second before he got caught. How long did he run? | 83.3 seconds |
| If Justin races his Chevy S-10 down Highway 37 for 2560 meters in 60 seconds, what is his average speed (velocity)? | 42.6 M/S |
| Mike rides his motorcycle at an average speed (velocity) of 20 meters/ second for 500 seconds, how far did he ride? | 10,000 Meters |
| Sarah backstrokes at an average speed of 8 meters per second, how long will it take her to complete the race of 200 meters length? | 25 Seconds |
| Lauren’s SUV was detected exceeding the posted speed limit of 60 kilometers per hour, how many kilometers per hour would she have been traveling over the limit if she has covered the a distance of 10 kilometers in 5 minutes? | 60 KM over the limit |
| Tinas calculations of the tarantula found that the spider was able to cover 20 centimeters in 5 seconds, what was the average speed of the spider? | 4 Cm/S |
| A coach wants to find out about the speed of the runners on a track team. Tell what simple equipment the coach needs in order to do this and explain what should be done. | The coach would need a mile long track and a stop watch, then he would need to time his players and see how long it takes them to complete the mile. Distance divided by time equals speed. |
| A roller coaster car rapidly picks up speed as it rolls down a slope. As it starts down the slope, its speed is 4 m/s. But 3 seconds later, at the bottom of the slope, its speed is 22 m/s. What is its average acceleration? | 6 M/S^2 |
| A cyclist accelerates from 0 m/s to 8 m/s in 3 seconds. What is his acceleration ? Is this acceleration higher than that of a car which accelerates from 0 to 30 m/s in 8 seconds? | 8/3 M/S^2 |
| A car advertisement states that a certain car can accelerate from rest to 70 km/h in 7 seconds. Find the car’s average acceleration. | 10Km/H/S |
| A lizard accelerates from 2 m/s to 10 m/s in 4 seconds. What is the lizard’s average acceleration? | 2 M/S^2 |
| If a Ferrari, with an initial velocity of 10 m/s, accelerates at a rate of 50 m/s/s for 3 seconds, what will its final velocity be? | 160 M/S |
| What is the correct formula for speed? | S= D/T |
| What is the correct formula for acceleration? | Acceleration= Final Velocity minus Initial Velocity over Time |
| It takes more force to overcome which of the following? Static Friction, Kinetic Friction | Static Friction |
| If an object is NOT moving the forces are _. | Balanced |
| Which is greater? Sliding Friction, Rolling Friction | Sliding Friction |
| Is this statement true or false? Acceleration can be positive or negative | True |
| What are factors when determining velocity? | Speed, Direction |
| The change in the position of an object is: | Displacement |
| What is the formula for force? | F = MA |
| Describe Newton’s first law of motion: | Newton's first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. |
| Define Newton’s second law of motion: | Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass. F = MA |
| Define Inertia: | The resistance of any physical object to any change in its velocity |
| What is the relationship between force, acceleration, and mass. | The greater the force that is applied to an object of a given mass, the more the object will accelerate. For example, doubling the force on the object doubles its acceleration. |
| What is the difference between Mass and Weight? | The mass is essentially "how much stuff" is in an object. With weight there is a gravitational interaction between objects that have mass. |
