What is Newton's First Law of Motion?

• The force of gravity is constant

• An object at rest stays at rest unless acted on by an outside force

• For every action, there is an equal and opposite reaction

• Force equals mass times acceleration

What role does friction play in motion?

• It slows down or stops objects

• It speeds up objects

• It only affects objects in water

• It has no effect on motion

What happens when forces are balanced?

• Objects accelerate

• Objects change direction

• Nothing happens

• Objects explode

What is inertia?

• The tendency of an object to resist changes in its motion

• The energy stored in an object

• The force that pulls objects towards the Earth

• The speed of an object in motion

What is the result of applying a larger force to an object?

Match the following

• 1st Law of Motion

• states that when one object applies a force to a second object, the second object applies an equal and opposite force to the first object.

• 2nd Law of Motion

• greater net force causes a greater acceleration for a given mass. For two objects with the same net force, the object with the greater mass accelerates less than the object with less mass.

• 3rd Law of Motion

• unless acted on by an unbalanced force, an object at rest stays at rest and an object in motion stays in motion at a constant velocity; unbalanced forces cause an object to accelerate (change direction or speed).
