CP Physics A Module 06

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv, where p is momentum, m is mass, and v is velocity.

Front

How do you calculate the momentum of an object?

Back

Momentum (p) is calculated using the formula p = mv, where m is the mass of the object and v is its velocity.

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 a collision is equal to the total momentum after the collision.

Front

What is an elastic collision?

Back

An elastic collision is a type of collision where both momentum and kinetic energy are conserved.

Front

What is an inelastic collision?

Back

An inelastic collision is a type of collision where momentum is conserved, but kinetic energy is not conserved.

Front

What is a recoil collision?

Back

A recoil collision occurs when two objects push away from each other, resulting in both objects moving in opposite directions.

Front

How do you find the final velocity of an object after a collision?

Back

To find the final velocity after a collision, use the conservation of momentum: m1v1 + m2v2 = m1v1' + m2v2', where m is mass and v is velocity.

Front

What is the formula for calculating the final velocity of two colliding objects?

Back

The final velocity can be calculated using the formula: v_f = (m1v1 + m2v2) / (m1 + m2) for perfectly inelastic collisions.

Front

What is the significance of negative velocity?

Back

Negative velocity indicates that an object is moving in the opposite direction to the defined positive direction.

Front

How do you determine the direction of momentum?

Back

The direction of momentum is the same as the direction of the object's velocity.
