An object accelerates if:

• It moves in a straight line at constant speed

• Its speed or direction changes

• It moves in a circle at constant speed

• It stops moving

Newton’s First Law is also known as:

• The law of force

• The law of motion

• The law of inertia

• The law of gravity

What is the formula for acceleration?

• Speed × time

• (Final velocity – Initial velocity) ÷ time

• Distance ÷ time²

• Mass ÷ time

Which force opposes motion between two surfaces?

• Gravity

• Friction

• Normal force

If the net force on an object is zero, the object:

• Accelerates

• Stays at rest or moves at constant speed

• Slows down

• Moves in a circular path

What happens to the acceleration of an object if the force on it is doubled?

• It is halved

• It doubles

• It remains the same

• It becomes zero
