Who formulated the three laws of motion?

• Albert Einstein

• Galileo Galilei

• Sir Isaac Newton

• Stephen Hawking

What happens to an object at rest if no external unbalanced force acts on it?

• It will start moving.

• It will remain at rest.

• It will accelerate.

• It will move at a constant velocity.

Which of the following best illustrates an object remaining at rest?

• A kicked soccer ball flying through the air.

• A rock that cannot be moved by a push.

• A golf ball rolling on the grass.

• An apple falling from a tree.

Which of the following best illustrates an object in uniform motion?

• A car parked on a street.

• A book lying on a table.

• A soccer ball kicked and moving through the air before hitting the ground.

• A person standing still.

What is Newton's First Law of Motion primarily about?

• The relationship between force, mass, and acceleration.

• The tendency of objects to resist changes in their state of motion.

• The action-reaction principle.

• The law of universal gravitation.

What happens to an object in uniform motion if no external unbalanced force acts on it?

• It will slow down and stop.

• It will change direction.

• It will continue in uniform motion.

• It will accelerate.

The property of an object to resist any change in its state of rest or uniform motion is called what?

• Momentum

• Inertia

• Acceleration

• Velocity

Newton's First Law of Motion is also commonly referred to as the Law of _____.

• Conservation of Energy

• Action and Reaction

What is necessary to change an object's state of rest or uniform motion?

• An internal force.

• A balanced force.

• An external unbalanced force.

• Gravity alone.

When a golf club hits a stationary golf ball, what causes the ball to move?

• The ball's internal energy.

• The force of gravity.

• An unbalanced force from the club.

• Air pressure.
