• balanced force

According to Newton’s third law of motion__________.

• Objects in motion will eventually stop
• Force is related to mass and velocity

• Every action has an equal and opposite reaction

According to Newton’s second law of motion___________.

• Objects in motion will eventually stop
• Force is related to mass and acceleration
• Gravity is a force that exists only between really large masses
• Sometimes action forces are equal in size and direction

According to Newton's first law of motion_____________.

• Sometimes action forces are equal in size and direction
• Gravity is a force that exists only between really large masses
• Objects in motion stay in motion/rest until acted on by an outside force
• Force is related to mass and acceleration

Acceleration is the _______________.

• change in motion of an object
• tendency of on object to resist changes in motion
• property of all moving objects
• the speed of something in a given direction
