Newton's Laws

If an object is at rest, there are no forces exerted on it.

An object only accelerates if there is an unbalanced force exerted on it

An asteroid moves at constant velocity through deep space. What forces are being exerted on it

A bicycle hits a parked truck. The bike feels a force of 50 N. What is the force on the truck?

A 210 kg car has an acceleration of -7 m/s². What force do the brakes exert on the road?

A soccer player kicks a ball to the right. It slows down after the kick. What direction is ΣF?

An object is accelerating to the left. The sum of the forces is

A man punches the wall. Who experiences the greater ACCELERATION?

What is the acceleration of a 5 kg bird which has a force of 50 N exerted on it?

A dog runs into a door. Who experiences the greater force

An object always moves in the direction of the sum of the forces.

What is the Third Law pair to the force the dog exerts on the chair?

A 20 kg child is accelerating down a hill on a sled at 0.5 m/s². What is the force?

A child leans on a skyscraper. Who experiences a greater force?

If an object is moving at constant velocity, the sum of the forces exerted on it is 0 N.

What acceleration would a 40 kg person have if they were pushed suddenly with 200 N?
