Newton's Laws

Newton's First law is...

• An object at rest remains at rest, and an object in motion tends to stay in motion

• The acceleration of an object is dependent on the mass of the object and the net force acting on it

• For every action there is an equal and opposite reaction

Newton's Second law is...

• An object at rest remains at rest, and an object in motion tends to stay in motion

• The acceleration of an object is dependent on the mass of the object and the net force acting on it

• For every action there is an equal and opposite reaction

Newton's Third law is...

• An object at rest remains at rest, and an object in motion tends to stay in motion

• The acceleration of an object is dependent on the mass of the object and the net force acting on it

• For every action there is an equal and opposite reaction

Motion cannot change without a(n) __________ force acting on it.

• balanced

• unbalanced

• strong

• weak

The more ________ the object has, the more new force has to be used to move it.

• weight

• friction

• mass

The size of the force on the first object _______ the size of the force on the second object.

• is the same as

• is less than

• is more than

• isn't comparable to

If the Earth is pulling down on you with a gravitational force of 500 N, you are also pulling up on the Earth with a gravitational force of 500 N.

• True

• False
