Momentum

Front

What is the unit for momentum?

Back

kg m/sec

Front

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

Back

mass and velocity

Front

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

Back

doubles

Front

Two skaters begin at rest. Skater 1 has a smaller mass than Skater 2. After they push off each other, Skater 1 __________ than Skater 2.

Back

has a greater speed

Front

When two objects collide, the P_before is __________ the P_after.

Back

equal to

Front

Define momentum.

Back

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

Front

What is the formula for calculating momentum?

Back

p = mv (where p is momentum, m is mass, and v is velocity)

Front

Explain the principle of conservation of momentum.

Back

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

Front

What happens to momentum in an elastic collision?

Back

Momentum is conserved, and both kinetic energy and momentum are transferred between the colliding objects.

Front

What happens to momentum in an inelastic collision?

Back

Momentum is conserved, but kinetic energy is not; some kinetic energy is transformed into other forms of energy.
