notebook P.83-97

What is the definition for speed? The distance an object travels in one unit of time
What is the definition for Acceleration? The rate at which velocity changes
What is the definition for Reference Point? A place or object used for comparison to determine if something is in motion
What is the definition for velocity? Speed in a given direction
What is the definition for average speed? Total distance traveled divided by the total time
What is the definition for constant speed? when the speed of the object does not change during a time period.
What is motion? The state in which one object's distance from another is changing
State three ways in which acceleration can change. Acceleration can change if the object speeds up, slows down, or changes direction.
How do we know motion has occurred? There must be a change in distance/position and a reference point
What do you do if you have two velocities in the same direction ex: 15 km/hr North and 3 km/hr North You need to add, The total velocity is 18 km/hr North
What do you do if you have two velocities in different directions? ex: 40 miles/hr North and 50 miles/hr South You need to subtract. The total velocity is -10 miles/hr
Calculate the answer: A cyclist travels 28 km during the first two hours of riding and 8 km during the next hour. What is the average speed? Show your work: 12 km/hour
A car traveling at 40m/s slows down to 20m/s over a period of 5 seconds. What is the cars acceleration? Show your work: 4m/s2
Which plane travels a greater distance: A plane that travels 6,000m/hr in 8 hours or one that travels or one that travels 12,000m/hr in 4 hours both travel the same distance 48,000m
If an object is traveling at constant speed, how can it accelerate? The object can speed up, slow down or change direction
Explain what a reference point is and why it is important A reference point is an object in the background that can be used to determine if an object is in motion. There must be a distance created between the object and the reference point in order for us to determine that motion has occurred.
What is the equation for speed? d/t
What is the equation for time? d/s
What is the equation for distance? s x t
what is the equation for average speed? total distance / total time
What is the equation for acceleration final velocity-initial velocity time
