1

The difference between weight and mass.

The mass of an object stays the same wherever it is but weight changes if an object goes to a place of stronger or weaker gravity.

2

Difference between and scalar and vector.

Scalar quantities a quantities which direction is not important. (Time\Mass)
Vector is a quantity were direction is important. (Force/Acceleration)

3

Difference between Distance and Displacement.

Distance is a SCALAR.
Displacement is a VECTOR.

4

Difference between VELOCITY and SPEED.

Velocity HAS a DIRECTION.
Speed does NOT have a DIRECTION.

5

Define Acceleration.

To speed up.

6

Define force

Is a push or pull upon an object.

7

Define Momentum

The strength or force that something had when it is moving.

8

Define Energy

Is the capacity for doing work. It exists as potential, kinetic, thermal, electrical, chemical, nuclear...

9

Distance/Time/Speed

Distance = Speed x Time
