Exploring Newton's Laws of Motion

What is the definition of motion?

• The speed of an object in any given direction.

• The state in which one object’s distance from another is changing.

• The amount of matter or substance that makes up an object.

• The tendency of an object to resist a change in motion.

What is inertia?

• The speed of an object in any given direction.

• The tendency of an object to resist a change in motion.

• The amount of matter or substance that makes up an object.

• The attractive force between objects.

Which of the following is an example of Newton's First Law?

• A ball rolling on the ground eventually stops due to friction.

• A rocket launching into space.

• A car accelerating when the light turns green.

• A swimmer pushing water backwards to move forward.

How does Newton's Second Law apply to a car accelerating?

• The car remains at rest until a force is applied.

• The car's acceleration is directly proportional to the net force applied and inversely proportional to its mass.

• The car exerts an equal and opposite force on the road.

• The car's speed remains constant unless acted upon by an unbalanced force.

What is an example of Newton's Third Law?

• A book resting on a table.

• A person walking, pushing the ground backwards.

• A car moving at a constant speed.

• A ball thrown upwards.

Which scenario best illustrates the concept of balanced forces?

• A car accelerating on a highway.

• A book lying still on a table.

• A ball rolling down a hill.

• A person pushing a box that starts to move.

What happens when unbalanced forces act on an object?

• The object remains at rest.

• The object moves at a constant speed.

• The object changes its state of motion.

• The object decreases in mass.

How does gravity affect motion?

• It causes objects to move uphill.

• It exerts a force that moves objects downhill.

• It has no effect on motion.

• It only affects objects in space.
