How to Calculate Momentum - Newton's 3rd Law of Motion - p=mv

This video tutorial covers Newton's Third Law of motion, focusing on the formula P = MV, where P is momentum, M is mass, and V is velocity. The tutorial explains how to use a triangle method to solve for any of the three variables when given the other two. It includes three practice problems: calculating momentum for a truck, finding the mass of a beach ball, and determining the velocity of a bowling ball. The video emphasizes understanding the relationship between mass, velocity, and momentum, and provides step-by-step solutions to enhance comprehension.

What does Newton's Third Law of Motion state?

• An object in motion stays in motion unless acted upon by an external force.

• For every action, there is an equal and opposite reaction.

• Energy cannot be created or destroyed, only transformed.

• The force of an object is equal to its mass times its acceleration.

In the formula P = MV, what does 'P' represent?

• Momentum

• Power

• Potential Energy

• Pressure

When using the triangle method, what operation do you perform to find mass if you know momentum and velocity?

• Multiply momentum by velocity

• Divide momentum by velocity

• Add momentum and velocity

• Subtract velocity from momentum

A truck with a mass of 4000 kg is moving at 10 m/s. What is its momentum?

• 400 kg m/s

• 4000 kg m/s

• 40,000 kg m/s

• 4,000,000 kg m/s

If a beach ball has a momentum of 0.25 kg m/s and is moving at 0.5 m/s, what is its mass?

• 1 kg

• 0.5 kg

• 0.25 kg

• 0.1 kg
