Impulse and Momentum Review

Front

The momentum of an object depends upon the object's ___________ & ___________.

Back

mass and velocity.

Front

Wearing a safety helmet is an effective way to protect your head from injury. In order for the force to ___________ on impact, the time to bring your head to a stop must ____________.

Back

decrease; increase.

Front

What type of collision occurs when total momentum and total kinetic energy remain constant during a collision?

Back

Elastic Collision.

Front

When the speed of an object is doubled, its momentum __________.

Back

doubles.

Front

Impulse is defined as the change in __________ of an object.

Back

momentum.

Front

Define impulse in terms of momentum.

Back

Impulse is the product of the average force applied to an object and the time duration over which the force is applied.

Front

What is the formula for momentum?

Back

Momentum (p) = mass (m) × velocity (v).

Front

What is the principle of conservation of momentum?

Back

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

Front

What happens to momentum in an inelastic collision?

Back

Total momentum is conserved, but total kinetic energy is not conserved.

Front

What is the difference between elastic and inelastic collisions?

Back

In elastic collisions, both momentum and kinetic energy are conserved; in inelastic collisions, only momentum is conserved.
