Unit 8- Laws of Motion & Forces

__ states that when one object exerts a force on a second object, the second object exerts a force on the first that is equal in strength & opposite in direction.

• 1st law of motion
• 2nd law of motion
• 3rd law of motion

The tendency of an object to resist any change in its motion.

• Inertia
• Centripetal acceleration
• Centripetal force
• Acceleration
• Air resistance

Acceleration toward the center of a curved or circular path.

• Centripetal acceleration
• Inertia
• Centripetal force
• Acceleration
• Air resistance

A force exerted toward the center of a curved path.

• Centripetal force
• Inertia
• Centripetal acceleration
• Acceleration
• Air resistance

States that an object moves at a constant velocity unless an unbalanced force acts on it.

• 1st law of motion
• 2nd law of motion
• 3rd law of motion

States that an object's acceleration is in the same direction as the net force on the object and is equal to the net force exerted on it divided by its mass.

• 1st law of motion
• 2nd law of motion
• 3rd law of motion

A property of a moving object resulting from its mass and velocity is _______

• Momentum
• Inertia
• Centripetal acceleration
• Centripetal force
• Acceleration

States that if no external forces acts on a group objects, their total momentum doesn't change.

• Law of conservation of momentum
• Inertia
• Centripetal acceleration
• Centripetal force
• Acceleration

A friction-like force that opposes the motion of the objects that move through the air.

• Air resistance
• Acceleration
• Terminal velocity
• Momentum
• Law of conservation of momentum

__ is an attractive force between any two objects that depends on the masses of the objects & the distance between them

• Gravity
• Acceleration
• Air resistance
• Terminal velocity
• Momentum
