Impulse is defined as the product of force and time during which the forces act, J = F.t.

Impulse is produced by a FORCE called :

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

Which option is correct for inelastic collision?

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

This equation represents :

For __________ collision, the total kinetic energy IS NOT CONSERVED. Some energy is lost and converted to other form of energy.

Coefficient of restitution : Is the ratio of the difference in velocities before and after the collision.

Which option is correct?



m₁u₁ + m₂u₂ = (m₁+m₂) v

This equation represents :

The value of coefficient of restitution, e_k is always

Choose the correct answer.

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
