Linear Momentum

Which equation correctly represents the relationship between linear momentum (p), mass (m), and velocity (v)?

• p = mv

• p = m/v

• p = v/m

• p = m + v

In a demonstration where an apple is placed on top of a basketball and both are dropped, the apple achieves a significantly higher upward velocity after the basketball bounces. What is the primary reason for this phenomenon?

• The apple's mass increases upon impact with the basketball.

• The basketball transfers a large portion of its momentum to the apple.

• The apple experiences a greater gravitational force than the basketball.

• The basketball absorbs all kinetic energy from the apple during the bounce.

A 5.0 kg sphere is initially at rest. Based on the principles of linear momentum, what is its momentum?

• Its momentum is constantly increasing.

• Its momentum is zero.

• Its momentum is equal to its mass.

• Its momentum cannot be determined without its acceleration.

An orange sphere with an initial momentum of 10 kg·m/s collides with a stationary green sphere. After the collision, the green sphere has a momentum of 7.5 kg·m/s. Assuming no external forces act on the system, what is the momentum of the orange sphere after the collision?

• 17.5 kg·m/s

• 10 kg·m/s

• 2.5 kg·m/s

• 0 kg·m/s
