Understanding Inertia

Who was the philosopher that believed objects naturally come to rest?

• Galileo Galilei

• Isaac Newton

• Aristotle

• Albert Einstein

What did Galileo believe about a ball's motion?

• It stops because it wants to be at rest

• It should roll on forever unless stopped by an external force

• It accelerates indefinitely

• It moves in a circular path

According to Newton's first law, what happens to an object in motion?

• It moves in a straight line

• It stops immediately

• It stays in motion unless acted upon by an unbalanced force

• It changes direction

Why does a car turn instead of moving straight due to inertia?

• Due to the wind resistance

• Because of the car's weight

• Due to the friction between the tires and the road

• Because of the driver's control

What is required to change the velocity of an object with high inertial mass?

• No force

• More force

• Constant speed

• Less force
