Momentum

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, representing the quantity of motion an object has.

Front

What is the formula for calculating momentum?

Back

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

Front

What are the units of momentum?

Back

The unit for momentum is kilogram meter per second (kg m/s).

Front

How does mass affect momentum?

Back

An increase in mass results in a proportional increase in momentum, assuming velocity remains constant.

Front

How does velocity affect momentum?

Back

An increase in velocity results in a proportional increase in momentum, assuming mass remains constant.

Front

Which has more momentum: a fast-moving object or a slow-moving object of the same mass?

Back

A fast-moving object has more momentum than a slow-moving object of the same mass.

Front

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

Back

If an object is at rest, its momentum is zero.

Front

What happens to the momentum of an object if its velocity doubles?

Back

If the velocity of an object doubles, its momentum also doubles, assuming mass remains constant.

Front

What is the relationship between momentum and collisions?

Back

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

Front

What is an elastic collision?

Back

An elastic collision is one in which both momentum and kinetic energy are conserved.
