Newton’s Second Law of Motion

What is Newton's First Law known as? The Law of

• Friction
• Mass
• Inertia
• Gravity

An object's velocity can be changed by changing its speed, its direction, or both.

• True
• False

The force that pulls an object in a circular motion and keeps it in a circular motion is centripetal force.

• True
• False

What happens when unbalanced forces act on an object at rest?

• the object remains at rest
• the object begins moving in an unpredictable direction
• the object begins moving in the direction of the net force
• the object begins moving opposite to the direction of net force

A ball is rolling on the floor and a force pushes it in the same direction, what will happen?

• The ball will go faster.
• The ball will slow down.
• The ball will stop. 
• The ball will fly in the air.

According to Newton's second law, if you increase the force applied to an object :

• it accelerates more
• it doesn't move
• you get more inertia
• it decelerates

A 50 kg bicycle accelerates at 2 m/s2. what was the force

• 150

• 125

• 100

• 200

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.

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

• True
• False
