Newton's Law

What is Newton's First Law of Motion also known as?

• The Law of Force

• The Law of Gravity

• The Law of Inertia

• The Law of Acceleration

What does the first part of Newton's First Law state?

• An object at rest stays at rest unless acted upon by an unbalanced force

• An object in motion stays in motion

• All objects have equal inertia

• Motion is caused by gravitational forces only

What is required to change the motion of an object according to Newton's First Law?

• Magnetic attraction

• A gravitational pull

• An unbalanced force

• A balanced force

What example is given to explain an object at rest?

• A math book on a desk

• A flying baseball

• A rolling ball

• A moving car

What does inertia mean?

• The gravitational pull on an object

• An object's resistance to change in its state of motion

• The speed of a moving object

• The force required to move an object

Which objects have more inertia?

• Bigger and heavier objects

• Objects at rest

• Lighter and smaller objects

• Objects in motion

What is friction described as?

• A magnetic force

• A type of gravitational force

• The resistance encountered when an object moves against another

• A force that only acts in space

What effect does friction have on a moving object?

• It increases its speed

• It changes its direction

• It has no effect

• It slows down and eventually stops the object

What additional force acts on a ball rolling down a sloped surface?

• Air resistance

• Electrical force

• Gravity

• Magnetic force
