Front

What is the law of conservation of momentum?

Back

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

Front

Define kinetic energy.

Back

The energy an object possesses due to its motion, calculated as KE = 1/2 mv².

Front

What is potential energy?

Back

The energy stored in an object due to its position or configuration, commonly gravitational potential energy.

Front

How do you calculate impulse?

Back

Impulse is calculated as the change in momentum, which is the product of force and the time duration of the force applied.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, Force = mass × acceleration (F = ma).
