CP Momentum Basics Review (23-24)

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 is the formula for calculating momentum?

Back

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

Front

What are the units of momentum?

Back

The units of momentum are kilogram meters per second (kg m/s).

Front

If an object is at rest, what is its momentum?

Back

If an object is at rest, its momentum is 0 kg m/s.

Front

How does mass affect momentum?

Back

The greater the mass of an object, the greater its momentum for a given velocity.

Front

How does velocity affect momentum?

Back

The greater the velocity of an object, the greater its momentum for a given mass.

Front

What happens to momentum in a closed system?

Back

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

Front

What is the relationship between momentum and force?

Back

Force is the rate of change of momentum; F = Δp/Δt, where F is force, Δp is change in momentum, and Δt is change in time.

Front

What is the unit for mass?

Back

The unit for mass is kilograms (kg).

Front

Which has more momentum: a moving car or a parked car?

Back

A moving car has more momentum than a parked car because momentum depends on velocity.
