Newton's Laws of Motion

The English Scientist who developed three laws of motion was called:

• Sir Isaac Newman

• Sir Isaac Newton

• Albert Einstein

• Mr. Fig Newton

Because of inertia, a resting object ________.

• will remain at rest

• will move at a constant speed

• will eventually move

• is unbalanced

The first law of motion states that objects in motion will:

• stop

• accelerate

• stay in motion

• rest

The first law of motion states that objects at rest will stay at rest unless acted upon by an unbalanced:

• motion

• force

• inertia

• acceleration

Newton's second law of motion states that an unbalanced force is equal to mass times:

• acceleration

• force

• motion

• inertia

NGSS.3-PS2-1

As more unbalanced force is applied to an object, its acceleration:

• stays the same

• decreases

• increases

Newton's third law of motion states that for every action there is:

• an opposite, but equal reaction.

• an opposite and equal reaction.

• a reaction.

If Mrs. Dircks dropped her Pepsi bottle, what is the force that pulls the bottle to the ground?

• motion

• friction

• air resistance

• gravity

Tags

NGSS.5-PS2-1

Friction and air resistance are forces that:

• can make an object slow down or stop

• pulls an object toward the center of Earth

• changes an object's position

• can't be described

A force is:

• a push

• a pull

• both

• neither
