Momentum

Front

What is momentum?

Back

Momentum is the quantity of motion an object has, calculated as the product of its mass and velocity.

Front

What is the formula for calculating momentum?

Back

Momentum (p) = mass (m) × velocity (v)

Front

Which has more momentum: a heavy object moving slowly or a light object moving quickly?

Back

The heavy object moving slowly may have more momentum if its mass compensates for its lower speed.

Front

What factors affect the momentum of an object?

Back

Momentum depends on the object's mass and velocity.

Front

If two objects have the same mass, which one has more momentum?

Back

The object with the higher velocity has more momentum.

Front

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

Back

If the velocity doubles, the momentum also doubles, assuming mass remains constant.

Front

Can an object have momentum if it is at rest?

Back

No, an object at rest has zero momentum because its velocity is zero.

Front

How does mass affect momentum?

Back

Greater mass results in greater momentum if velocity is constant.

Front

What is the relationship between momentum and a collision?

Back

In a collision, momentum is conserved; the total momentum before the collision equals the total momentum after.

Front

What is the difference between elastic and inelastic collisions in terms of momentum?

Back

In elastic collisions, both momentum and kinetic energy are conserved; in inelastic collisions, only momentum is conserved.
