|
Velocity
|
Tells you an objects speed and direction. (m/s)
|
|
|
Speed
|
Average speed (m/s) = Distance travelled (m) / Time taken (s)
|
|
|
Distance-Time Graphs
|
Steep slope = Fast speed Straight line = Stationary
Curved line = Changing |
|
|
Speed-Time Graphs
|
Steep line = Accelerating
Stationary = Constant speed |
|
|
Acceleration
|
Acceleration (m/s2) = Change in speed (m/s) / Time taken (s)
|
|
|
Forces
|
When two objects interact. Forces in an interaction pair are equal in size and opposite in direction and they act on different objects.
|
|
|
Friction and Reaction
|
Friction is when two objects experience a force that tries to stop them working.
Friction forces are equal in size. |
|
|
Forces and Motion
|
The size of the arrows show the size of the force and the direction shows the direction the force is acting in.
If more than one force is acting on an object in the same direction they'll add up and in opposite they'll subtract making the resultant force. |
|
|
Momentum
|
Momentum (kg m/s) = Mass (kg) * Velocity (m/s)
