Momentum, Collisions, Impulse, Conservation of Momentum

Front

What is impulse?

Back

Impulse (J) is defined as the product of the average force (F) applied to an object and the time duration (t) over which the force is applied. The formula is J = F x t.

Front

What is the formula for momentum?

Back

Momentum (p) is defined as the product of mass (m) and velocity (v). The formula is p = m x v.

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 does conservation of momentum state?

Back

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

Front

What is a perfectly inelastic collision?

Back

A perfectly inelastic collision is a type of collision where two objects stick together after colliding, moving as a single object.

Front

What is an elastic collision?

Back

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

Front

How do you calculate the change in momentum?

Back

The change in momentum (Δp) can be calculated using the formula Δp = p_final - p_initial.

Front

What is the relationship between impulse and momentum?

Back

Impulse is equal to the change in momentum of an object. This is expressed as J = Δp.

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 energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
