Understanding Momentum

What is the definition of momentum?

• Momentum is the force applied over time.

• Momentum is the change in energy of an object.

• Momentum is the product of mass and velocity.

• Momentum is the distance traveled in a given time.

How is momentum calculated in physics?

• p = m * v

• p = m - v

• p = m + v

• p = m / v

What are the units of momentum?

• kg·m^2/s

• kg·m/s

• g·m/s

• kg/s

Why is momentum considered a vector quantity?

• Momentum is a vector quantity because it is always positive.

• Momentum is considered a vector quantity because it is the sum of forces acting on an object.

• Momentum is considered a vector quantity because it is the product of mass and velocity, and velocity is a vector.

• Momentum is a scalar quantity because it only depends on mass.

How does momentum relate to Newton's second law of motion?

• Momentum decreases with increasing velocity.

• Momentum relates to Newton's second law as the rate of change of momentum is equal to the net force acting on an object.

• Momentum is unrelated to force.

• Momentum is the same as mass.
