This type of friction occurs between two objects that are not moving
What is static friction?
Newton's First Law is also called the Law of ___________
What is Inertia?
The force of a 2 kg skate board that is accelerating at 3 m/s/s
What is 6 N?
Resistance to change
What is inertia?
Force is described as a ____________ or a ____________.
What is a push or a pull?
Pushing your book across the table is this type of friction
What is sliding friction?
What could to do to the mass of a shopping cart if you wanted to decrease the acceleration?
What is Increase the mass?
You push a desk to the left with 15 N and your friend helps you by pushing to the left with 10 N. This is the net force
What is 25 N to the left?
The amount of matter in an object
What is mass?
The sum of all forces acting on a object
What is net force?
A ball rolling across the turf is an example of this type of friction
What is rolling friction?
Newton's Third Law states that every action has an equal and ____________ reaction.
What is opposite?
A ball hits a wall with a force of 7 N. This is the force of the wall pushing the ball back.
What is 7 N?
The two things that affect the force of gravity are mass and this
What is distance?
This type of force will cause movement
What is unbalanced force or nonzero net force?
What is fluid friction?
The formula to solve for force
What is mass x acceleration?
The acceleration of a 50 kg car if a 100 N force acts on it
What is 2 m/s/s?
The measure of the force of gravity on an object
What is weight?
Your dog pulled on their leash with a force of 10 N to the right, you pull to the left with 5 N. What is the net force?
What is 5 N to the right?
Two ways to increase friction is to push two object harder together or do this
