Question

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank

Answer 1

Explanation :

There are two types of collision i.e. elastic and elastic collision.

• Elastic collision : In this type of collision, the total momentum and the kinetic energy of the particles remains constant.
• Inelastic collision : In this type of collision, only the momentum remains constant while there is some loss of kinetic energy occurs.

From Newton's second law,

F = m a

a is the rate of change of velocity.

$F=m\dfrac{v}{t}$

There is a inverse relation between the force and the time of collision.

The change in momentum will remain the same during a collision, the force needed to bring an object to a stop can be increased if the time of the collision is decreased.

Answer 2

Answer:momentum,decreased and increased
