Momentum and Collisions

Front

What is an inelastic collision?

Back

An inelastic collision is a type of collision in which the total kinetic energy is not conserved, although momentum is conserved.

Front

What happens to kinetic energy in an inelastic collision?

Back

In an inelastic collision, some kinetic energy is transformed into other forms of energy, such as heat or sound.

Front

What is the principle of conservation of momentum?

Back

The principle of conservation of momentum states that the total momentum of a closed system remains constant if no external forces act on it.

Front

How do you calculate momentum?

Back

Momentum (p) is calculated using the formula p = mass (m) × velocity (v).

Front

What are the units of momentum?

Back

The units of momentum are kg*m/s.

Front

What is the relationship between mass and inertia?

Back

Inertia is the property of an object to resist changes in its state of motion, and it is directly related to the mass of the object; greater mass means greater inertia.

Front

What is the formula for calculating the momentum of an object?

Back

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

Front

What is the significance of a heavier object in motion compared to a lighter object?

Back

A heavier object in motion has greater momentum than a lighter object moving at the same speed, making it harder to stop.

Front

What are the units for mass?

Back

The units for mass are kilograms (kg).

Front

When is it easier to stop a fast-moving object compared to a slow-moving one?

Back

It is easier to stop a fast-moving object if it is lighter than a slow-moving object that is heavier.
