Motion Review
| Interrogative Query | Sufficient Response |
|---|---|
| What is velocity? | Speed and Direction |
| What is speed? | Distance and time |
| Explain displacement. | How far something is from its original location |
| What is distance? | The space between two points, or locations |
| Explain acceleration. Tell three ways an object can accelerate. | Acceleration is changing in speed. Gaining speed, losing speed, or changing direction |
| Explain why deceleration is also acceleration. | Deceleration is acceleration because acceleration is any change in speed |
| What does a flat line on a distance/time graph represent? | Time passing but, distance is not changing |
| Greater slope up means ____________ on a distance/time graph. | Greater Distance from original location |
| Greater slope down means ____________ on a distance/time graph. | Lesser Distance from original location |
| What does a flat line on a velocity/time graph represent? | Velocity is constant while time is passing |
| What does an upward slope on a velocity/time graph represent? | Acceleration |
| What does a downward slope on a velocity/time graph represent? | Deceleration or Acceleration |
| What does constant velocity mean? | Consistent direction and speed |
| Tell three ways velocity can change. | Lose speed, Gain speed, or change in direction |
| If an object’s mass increases, its acceleration will ______________. | Increase |
| Force = _________ x ____________ | Mass x Acceleration |
| What are unbalanced forces? | The net force of balances not equal to 0 |
| What are balanced forces? | The net force of balances equal to 0 |
| Net force = _______________ | The sum of all forces on an object |
| What type of force does not cause acceleration? | Balanced |
| What is magnitude? | Measurement of maximum motion |
| What is vector? | Having direction as well as magnitude |
| Explain Newton’s First Law of Motion. | Any object in motion will stay in motion until an outside unbalanced force acts upon it |
| Greater mass = __________ inertia | Greater intertia |
| Explain Newton’s Second Law of Motion. | When a force acts on an object the object will accelerate in the direction of the force |
| Explain Newton’s Third Law of Motion. | For every force or reaction there is an equal and opposite force or reaction |
| What is inertia? | The tendency to remain the same |
| What is another name for Newton’s First Law of Motion? | Newton’s first law of inertia |
| What does air resistance depend upon? | The speed and surface area of an object |
| What is the formula for velocity? | Distance/Time |
| What is the difference between speed and velocity? | Velocity includes speed and direction Speed does not include direction but distance and time |
| What is the difference between mass and weight? | Mass is the amount of matter in an object Weight is how heavy something is |
| How does your mass on Earth compare to your mass on the moon? | It is the same |
| How does your weight on Earth compare to your weight on the moon? | It is less because there is less gravity |
| Explain friction. How does it affect the movement of an object? | Friction is the resistance based on what the surface is made out of. It slows objects down |
| How does the mass of an object affect the amount of force needed to accelerate the object? | It increases it |
| Explain how to solve a vector diagram (to determine a net force). | Subtract to find the difference |
