What is acceleration?

• A type of force

• A change in velocity

• A measurement of mass

• The speed in a specific direction

According to Newton's first law, what will an object at rest do?

• Move randomly

• Decrease in mass

• Stay at rest unless acted upon by an outside force

• Accelerate on its own

What does Newton's second law of motion state?

• Acceleration is due to gravity only

• Mass equals force times acceleration

• Force equals mass times acceleration

• Force equals mass divided by acceleration

Which of the following best describes the relationship between force, mass, and acceleration?

• Force is directly proportional to acceleration and inversely proportional to mass

• Force is inversely proportional to mass and acceleration

• Force is directly proportional to mass and inversely proportional to acceleration

• Force is directly proportional to both mass and acceleration

How does the mass of an object affect the force needed to move it?

• Mass has no effect on the force needed

• More mass requires more force

• Less mass requires more force

• Only velocity affects the force needed

What does Newton's third law of motion describe?

• The effect of gravity on motion

• The relationship between mass and acceleration

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

• Objects at rest will remain at rest
