Understanding Motion: Aristotle vs. Newton

According to Aristotle, why is an object in uniform circular motion not considered to be accelerating?

• Because it is slowing down

• Because it is changing direction

• Because it is moving in a straight line

• Because its speed is constant

What did Newton believe about an object moving in a circular path at a constant speed?

• It is accelerating due to a change in direction

• It is not accelerating

• It is accelerating due to a change in speed

• It is not affected by any force

What must be present for an object to change its speed or direction, according to Newton?

• A change in mass

• A change in volume

• A force

• A change in temperature

What happens to an object in circular motion if the force maintaining it is removed?

• It continues in a circular path

• It stops immediately

• It moves in a straight line at a constant speed

• It speeds up

According to Newton's first law, what is the natural tendency of an object in the absence of forces?

• To move in a straight line at a constant speed

• To move in a circular path

• To remain stationary

• To accelerate
