1

Q

Define Momentum

A

the quantity of motion of a moving body, measured as a product of its mass and velocity. (How hard it is to stop an object)

2

Q

Momentum (p) =

A

Mass (m) x Velocity (v)

3

Q

Is momentum vector or scalar

A

vector

4

Q

Change in momentum (mv-mu) =

A

Force(F) x time(s)

5

Q

Force x time (change in momentum) =

A

Impulse

6

Q

Impulse

A

The effect of a force

7

Q

Principle of conservation of momentum

A

In a closed system, the total momentum before a collision is equal to the total momentum after a collision
