What is Newton's First Law

True or False. Acceleration of an object is directly proportional to the net force acting on it?

What is the net force?

A ____________ is a push or a pull on an object.

When the vectors (arrows) point away what function do you use?

The more mass an object has, the _______ force it takes to accelerate it.

What is the net force required to accelerate a 20 kg bike accelerates at 10 m/s²?

(Using F_net=ma), What net force is required to accelerate a car at a rate of 2 m/s² if the car has a mass of 3,000 kg?

(Use F_net=ma), A 10 kg bowling ball would require what force to accelerate down an alleyway at a rate of 3 m/s²?

(Use F_net=ma). Sally has a car that accelerates at 5 m/s². If the car has a mass of 1,000 kg, how much force does the car produce?

(Use F_net=ma). What is the mass of a falling rock if it produces a force of 147 N? (Acceleration due to gravity = 9.8 m/s²)

(Use F_net=ma). What is the mass of a truck if it produces a force of 14,000 N while accelerating at a rate of 5 m/s²?

(Use F_net=ma). What is the acceleration of a softball if it has a mass of 0.5 kg and hits the catcher's mitt with a force of 25 N?

(Use F_net=ma). Your parents' car has a mass of 2,000 kg. If your car produces a force of 5,000 N, at what rate will it accelerate?

(Use F_net=ma). Use the diagram to determine the net force, assume the object is accelerating at a rate of 3 m/s², and determine the object's mass?

(Use F_net=ma). Use the diagram to determine the net force, assume the object is accelerating at a rate of 2 m/s². What amount of mass does the object have?

If the man pushes with an equal amount of force, which object will accelerate more?

If the mass of the car/man/parachute is 150 kg, what is their acceleration?

Which has the MOST inertia?

Which one has the LEAST inertia?
