What is Newton's First Law known as? The Law of
Inertia
What is Newton's second law of motion?
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Newton's _____ Law of Motion means that for every force there is a reaction force that is equal in size, but opposite in direction.
Third
Which has more Inertia? (so need more force to move)
Truck
Who Came up with the laws of motion?
Issac Newton
The ____ of an object is the force of gravity on the object.
weight
What two factors do you use to describe a force?
strength and direction
Example: If you use the same force to push a truck and push a car which one will have more acceleration and why?
The car because it has less mass
When a heavy football player and a light one run into each other, who exerts more force?
They are equal
Which type of force(s) will cause a change in an object's motion?
unbalanced forces
Which is easier? pushing an empty shopping cart or a full shopping cart? why?
The empty one because it has less mass
Newton's third law states that any action will have a(n) _______ and ______ reaction
Equal and opposite
An object in motion will stay in what kind of motion as long as the net forces acting on it are zero?
constant motion in a straight line
Mike's car, which weighs 1,000 kg, is out of gas. Mike is trying to push the car to a gas station, and he makes the car go 0.05 m/s/s. Using Newton's Second Law, you can compute how much force Mike is applying to the car
50 newtons
