Understanding Newton's First Law of Motion

What does Newton's First Law state about an object with zero net force?

• It will accelerate.

• It will move in a circular path.

• It will remain at rest or in uniform motion.

• It will change its velocity.

In the example of the apple on the table, what can be inferred if there is no acceleration?

• The net force is zero.

• The apple is accelerating.

• The net force is non-zero.

• The apple is moving.

When a car is moving at a constant speed of 65 mph, what does Newton's First Law imply about the forces acting on it?

• The net force is zero.

• The car is decelerating.

• The car is accelerating.

• The forces are unbalanced.

What is a common misconception about motion that Newton's First Law addresses?

• Objects do not need force to stop.

• Objects move in circles without force.

• Objects naturally speed up.

• Objects need a force to keep moving.

What does the concept of inertia describe?

• An object's tendency to move in circles.

• An object's tendency to maintain its velocity.

• An object's tendency to change its velocity.

• An object's tendency to stop moving.

Which of the following is true about inertia?

• Inertia is a force.

• Inertia is a property of matter.

• Inertia causes objects to stop.

• Inertia is only present in moving objects.

How does mass relate to inertia?

• More mass means less inertia.

• Mass does not affect inertia.

• More mass means more inertia.

• Inertia is independent of mass.

What happens to an object with no external forces acting on it, according to Newton's First Law?

• It will continue moving at a constant velocity.

• It will accelerate.

• It will eventually stop.

• It will move in a random direction.

What is the role of friction in the context of Newton's First Law?

• Friction is a force that speeds up objects.

• Friction is a force that stops objects.

• Friction is a force that balances other forces.

• Friction has no effect on motion.

Why does the Earth continue to spin on its axis?

• Due to its inertia and lack of opposing forces.

• Due to air resistance.

• Because of a constant external force.

• Because of gravitational pull.
