Elastic and Inelastic Collisions Review

Front

What does the momentum of an object depend on?

Back

The momentum of an object depends on its mass and velocity.

Front

Which object has a larger final speed when a 60 kg student stands up at 2 m/s in a 5 kg chair?

Back

The chair has a larger final speed.

Front

What occurs during a collision?

Back

A collision occurs when two or more objects hit each other with a force.

Front

What does an object's inertia depend on?

Back

An object's inertia depends on the weight or mass of the object.

Front

In the presence of unbalanced forces, in which direction will an object move?

Back

The object will move in the direction that the larger force is being applied.

Front

Define elastic collision.

Back

An elastic collision is one in which both momentum and kinetic energy are conserved.

Front

Define inelastic collision.

Back

An inelastic collision is one in which momentum is conserved, but kinetic energy is not.

Front

What is the law of conservation of momentum?

Back

The law of conservation of momentum states that the total momentum of a closed system remains constant if no external forces act on it.

Front

What happens to kinetic energy in a perfectly inelastic collision?

Back

In a perfectly inelastic collision, the objects stick together, and kinetic energy is not conserved.

Front

What is the formula for momentum?

Back

The formula for momentum (p) is p = mass (m) × velocity (v).
