Question | Answer |
---|---|
Rate of change in position (no direction) | Speed |
Rate of change in position (with direction) | Velocity |
Rate of change in velocity | Acceleration |
m/s | Velocity |
Sum of all forces on an object | Net Force |
m/s/s | Acceleration |
Newtons | Force |
meters | Distance/Displacement |
Used to represent velocity | Distance-Time Graph |
Used to represent acceleration | Velocity-Time Graph |
Represented by a horizontal line on a distance-time graph | Not moving |
Represented by a horizontal line on a velocity-time graph | Moving at a constant speed |
Represented by a straight line going up and to the right on a distance-time graph | Moving at a constant speed |
Represented by a straight line going up and to the right on a velocity-time graph | Speeding up at a constant rate |
Represented by a curve going to the right and up on a distance-time graph | Speeding up at a constant rate |
This word describes an object's resistance to change its motion | inertia |
Inertia is closely connected to this property of matter | mass |
The force of gravity pulling on an object | weight |
The amount of matter in an object | mass |
The amount of space an object occupies (takes up) | volume |
Joules | energy |
Watts | Power |
Required to change the velocity of an object | Net Force |
Law of Physics that describes inertia | Newton's First Law |
Ratio of force to mass | acceleration |
Can be calculated by squaring velocity and multiplying by mass | kinetic energy |
Ratio of change in velocity to time | acceleration |
Ratio of distance to time | velocity/speed |
Ratio of mass to volume | density |
Can be increased to increase inertia | mass |
3 ways to change velocity | speed up, slow down, change direction |
Force that goes in the opposite direction of motion when matter touches | friction |
