Physics Collisions Flashcard

Front

What is impulse in physics?

Back

Impulse is the integral of the net force on an object over time, representing the product of force and time.

Front

How is force related to momentum in a collision?

Back

Force is equal to the change in momentum over time.

Front

What occurs during an inelastic collision?

Back

In an inelastic collision, momentum is conserved, but kinetic energy is not.

Front

State Newton's third law of motion.

Back

Every action has an equal and opposite reaction.

Front

What happens in an elastic collision?

Back

In an elastic collision, both momentum and kinetic energy are conserved.

Front

Define momentum in physics.

Back

Momentum is the product of an object's mass and its velocity.

Front

What is the formula for calculating impulse?

Back

Impulse = Force × Time.

Front

Explain 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.

Front

What is the principle of conservation of momentum?

Back

The total momentum of a closed system remains constant if no external forces act on it.

Front

How does the concept of impulse relate to changes in momentum?

Back

Impulse is equal to the change in momentum of an object.
