What does it mean for an object to accelerate?

• It stays at a constant speed.

• It moves in a circle.

• It changes its velocity.

• It remains at rest.

According to Newton's First Law, what happens to an object in motion if no net force acts on it?

• It changes direction.

• It accelerates.

• It stops moving.

• It continues moving at constant velocity.

What is the key difference between velocity and speed?

• Speed includes direction, velocity does not.

• Velocity includes direction, speed does not.

• Speed is always greater than velocity.

• Velocity is always greater than speed.

In the flowchart, what happens if the net force on an object is zero and it was initially at rest?

• It starts moving.

• It accelerates.

• It changes direction.

• It remains at rest.

Why is wearing a seat belt important according to Newton's First Law?

• It applies a net force to your body, preventing you from continuing to move forward.

• It helps the car stop faster.

• It makes the car go faster.
