|
Distance: |
Scalar quantity that refers to the amount of "ground covered"; ignorant of direction |
|
|
Displacement |
Vector quantity that tells how far out of place an object is; relies on direction. |
|
|
Speed |
Scalar quantity; how fast an object is moving |
|
|
Velocity |
Vector quantity; the rate at which an object changes its position. |
|
|
Average distance formula |
Total distance/total time |
|
|
Average velocity formula |
Displacement/time |
|
|
Factors that cause a change in velocity |
Speed and direction |
|
|
Acceleration |
Vector quantity; rate of change in velocity. |
|
|
Two types of acceleration |
Constant and average acceleration |
|
|
Final/initial velocity formula |
V=U+AT V: final velocity U: initial velocity A: acceleration T: time |
|
|
Pressure |
Measurement of force on a surface SI is the Pascal (Pa) = force/area |
|
|
Momentum |
Vector quantity Measurement of mass in motion (p) p= mass x velocity SI is kg*m/s |
|
|
Impulse |
A change in momentum. (J) = force x time Impulse(J) = mass * change in velocity Impulse(J) = Force * change in time SI = N/s |
|
|
Momentum conservation formula |
Used for collision problems M1*v1=-m2*v2
|
|
|
Work |
Measured in Energy (joules or j) Force * distance |
|
|
Power |
Measured in Watts (W) Work/time |
