momentum

Front

What is momentum?

Back

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

Front

What is the formula for calculating momentum?

Back

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

Front

What are the units of momentum?

Back

The units of momentum are kg·m/s.

Front

Which has more momentum: a car at a stop light or a bike moving at 15 mph?

Back

The bike has more momentum.

Front

If an object has a mass of 2 kg and is moving at a velocity of 3 m/s, what is its momentum?

Back

The momentum is 6 kg·m/s.

Front

What happens to momentum when the mass of an object increases while its velocity remains constant?

Back

The momentum increases.

Front

What happens to momentum when the velocity of an object increases while its mass remains constant?

Back

The momentum increases.

Front

If a 0.250 kg cart is moving at 0.400 m/s, what is its momentum?

Back

The momentum is 0.1 kg·m/s.

Front

What is the relationship between momentum and force?

Back

Force is the rate of change of momentum over time.

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.
