Newton's Laws Quiz Review

Newton's First Law States....

• The force acting on an object is equal to the objects mass and acceleration.

• An object in motion will slow down to a stop.

• An object in motion remains in motion, with the same speed and direction, unless acted upon by an unbalanced force.

• Acceleration is when an object is speeding up.

• 0.96 N
• 0.12 N
• 1.20 N
