Unit 4 - Momentum

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 = m * v, 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

How does mass affect momentum?

Back

Increasing the mass of an object increases its momentum, assuming velocity remains constant.

Front

How does velocity affect momentum?

Back

Increasing the velocity of an object increases its momentum, assuming mass remains constant.

Front

Is momentum a scalar or vector quantity?

Back

Momentum is a vector quantity, meaning it has both magnitude and direction.

Front

What happens to momentum if both mass and velocity are doubled?

Back

If both mass and velocity are doubled, momentum increases by a factor of four.

Front

Calculate the momentum of a 0.250 kg cart moving at 0.400 m/s.

Back

The momentum is 0.1 kg-m/s.

Front

What is the effect on momentum if mass is doubled and velocity is halved?

Back

The momentum stays the same.

Front

What is the relationship between momentum and kinetic energy?

Back

Momentum and kinetic energy are related, but they are different concepts; kinetic energy depends on the square of velocity.
