Momentum

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity. It is a vector quantity, meaning it has both magnitude and direction.

Front

What is the formula for calculating momentum?

Back

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

Front

How does mass affect momentum?

Back

The greater the mass of an object, the greater its momentum, assuming velocity remains constant.

Front

How does velocity affect momentum?

Back

The greater the velocity of an object, the greater its momentum, assuming mass remains constant.

Front

What happens to momentum in a collision?

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 the difference between elastic and inelastic collisions?

Back

In elastic collisions, both momentum and kinetic energy are conserved. In inelastic collisions, momentum is conserved, but kinetic energy is not.

Front

What is the unit of momentum?

Back

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

Front

If two objects have the same mass, how does their speed affect their momentum?

Back

The object with the higher speed will have greater momentum.

Front

What is the relationship between force and momentum?

Back

A net force acting on an object causes a change in momentum over time, described by the equation: Force = change in momentum / time.

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time. It is equal to the product of the average force and the time duration.
