Collisions and Momentum

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv.

Front

What does Newton's third law state?

Back

For every action, there is an equal and opposite reaction.

Front

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.

Front

What is an elastic collision?

Back

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

Front

What is an inelastic collision?

Back

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

Front

What happens to kinetic energy in a perfectly inelastic collision?

Back

In a perfectly inelastic collision, the colliding objects stick together, and some kinetic energy is transformed into other forms of energy.

Front

How does mass affect momentum?

Back

An increase in mass will increase momentum if velocity remains constant.

Front

How does velocity affect momentum?

Back

An increase in velocity will increase momentum if mass remains constant.

Front

What is the formula for calculating momentum?

Back

The formula for momentum is p = mv, where p is momentum, m is mass, and v is velocity.

Front

What is the significance of impulse in collisions?

Back

Impulse is the change in momentum resulting from a force applied over time, and it is crucial in understanding how collisions affect objects.
