Newton's Law of Motion

An object at rest will _______ if no outside forces are applied.

• Stay at rest
• Increase Velocity
• Decrease Mass

A greater applied force is required to move an object with a greater mass than one with a smaller mass.

• True
• False

According to Newton’s first law of motion, a moving object that is not acted on by an unbalanced force will

• remain in motion.
• eventually come to a stop.
• change its momentum.
• accelerate.

How does Newton’s third law explain how a rocket takes off?

• The rocket’s acceleration is positive, while the gasses acceleration is negative but the direction is the same. 
• The rocket is at rest until ignition.
• The hot gasses move in one direction, while the rocket moves in the opposite direction but with equal force.

Acceleration is caused by a force acting on a mass.

• Newton’s first law of motion
• Newton’s second law of motion
• Newton’s third law of motion

For a force on an object there is an equal and opposite force.

• Newton’s first law of motion
• Newton’s second law of motion
• Newton’s third law of motion

Without any force to change it, an object at rest stays at rest and an object in motion stays in motion

• Newton’s first law of motion
• Newton’s second law of motion
• Newton’s third law of motion

If a force of 26 N is exerted on two balls, one with a mass of 0.52 kg and the other with a mass of 0.78 kg, which ball will have the greater acceleration?  (F=ma)

• The one with a mass of .78 kg will have the greatest acceleration.
• The one with a mass of .52 kg will have the greatest acceleration.
• They will both accelerate at the same rate.
