Impulse and Momentum

Front

What is the definition of Impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time. It is calculated as the product of the average force and the time duration over which the force acts.

Front

What is the formula for Momentum?

Back

Momentum (p) is defined as the product of an object's mass (m) and its velocity (v): p = m * v.

Front

What is the principle of conservation of momentum?

Back

The principle of conservation of momentum states that in a closed system, the total momentum before an event (like a collision) is equal to the total momentum after the event.

Front

What is the unit of momentum?

Back

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

Front

How does mass affect momentum?

Back

Momentum is directly proportional to mass. If the mass of an object increases while its velocity remains constant, its momentum will increase.

Front

What is the relationship between impulse and momentum?

Back

Impulse is equal to the change in momentum of an object. Mathematically, Impulse = Δp = p_final - p_initial.

Front

What happens to momentum in an elastic collision?

Back

In an elastic collision, both momentum and kinetic energy are conserved.

Front

What happens to momentum in an inelastic collision?

Back

In an inelastic collision, momentum is conserved, but kinetic energy is not conserved.

Front

What is the formula for calculating impulse?

Back

Impulse (J) can be calculated using the formula: J = F * Δt, where F is the average force applied and Δt is the time duration.

Front

What is the effect of a larger force on impulse?

Back

A larger force applied over the same time duration results in a greater impulse, leading to a larger change in momentum.
