Momentum is given by the formula p = mv. Choose the correct answer below :

• p = power , m = mass , v = velocity

• p = momentum , m = motion , v = volume

• p = power , m = mass , v = volume

• p = momentum , m = mass , v = velocity

The SI unit for linear momentum is :

• kg m s^-2

• kg m/s

• kg m s

• kg/m s

Impulse can be determined by calculating the area under graph of

• force (f) - time (t) graph

• impulse (J) - time (t) graph

• momentum (p) - time( t) graph

• velocity (v) - time (t) graph

After collision, the two objects move off with different velocity. What type of collision is this?

• Inelastic

• Elastic

Choose the correct answer. (scroll down)

I) momentum is a vector quantity

II) direction of momentum is the same as direction of weight

III) impulse is the change of momentum

iv) momentum increases when the velocity of a body increases

• I and II only

• I and III only

• I , II and III only

• I , III and IV only

An expression for Force of Gravity is

• F_g = mg

• F_g = 9.8 m/s²

• F_g = (Gm₁m₂)/d²

• F_g = F_N
