Define momentum in the context of collisions.

Back

Momentum is the product of an object's mass and its velocity, and it is conserved in isolated systems.

What is the principle of conservation of momentum?

Back

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

What is kinetic energy and how is it calculated?

Back

Kinetic energy is the energy of an object in motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

What is potential energy and how is it calculated?

Back

Potential energy is the stored energy of an object due to its position or state, commonly calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

What is the difference between elastic and inelastic collisions?

Back

In elastic collisions, both momentum and kinetic energy are conserved; in inelastic collisions, momentum is conserved but kinetic energy is not.
