Newton's Laws

What is Newton's 1st Law?

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

• An object at rest will stay at rest, an object in motion will stay in motion, unless an unbalanced force acts upon it.

What is Newton's 3rd Law?

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

• Acceleration depends on two variables, the mass of the object and the amount of force.

Newton's first law states that an object must travel at a constant speed and in ___________, unless an unbalanced force acts on it.

• in a circle

• a wave like manner

• the same direction

Suppose an Astronaut floating in space throws a rock. What will happen to the rock?

• It will continue to move in the same direction, speeding up as it moves.

• It will continue to move at the same speed and in the same direction until it is acted upon by another force.
