Exploring Newton's First Law of Motion

Why are Newton's Laws particularly important in introductory physics?

• They are not important in physics.

• They explain the behavior of light.

• They are only relevant to advanced physics.

• They describe the motion of particles in the universe.

According to Newton's First Law, what happens to an object at rest?

• It changes direction.

• It accelerates.

• It stays at rest.

• It starts moving.

What is the key condition for an object in motion to stay in motion according to Newton's First Law?

• Absence of external forces.

• Presence of external forces.

• Constant acceleration.

• Changing velocity.

In the example of Olympic curling, what happens to the stone if there is no friction?

• It slows down.

• It stops immediately.

• It moves at the same speed.

• It speeds up.

What does Newton's First Law imply about the net force acting on an object?

• The net force is variable.

• The net force is negative.

• The net force is zero.

• The net force is always positive.

If an object has no change in velocity, what can be said about its acceleration?

• It has no acceleration.

• It has negative acceleration.

• It has variable acceleration.

• It has positive acceleration.

What happens to a car moving at constant speed in a straight line in terms of acceleration?

• It has no acceleration.

• It has centripetal acceleration.

• It has negative acceleration.

• It has positive acceleration.

What is the direction of acceleration when a car is moving in a circle at constant speed?

• Towards the center of the circle.

• Away from the center of the circle.

• In the direction of motion.

• Opposite to the direction of motion.

Why does a car slow down when the gas pedal is released, despite moving at constant velocity before?

• Because of the net force being zero.

• Because of the increase in mass.

• Because of the presence of friction and air resistance.

• Because of the absence of gravity.
