What is a balanced force?
What is a force?
What is a push or pull on an object?
This law states that objects in motion stay in motion and objects at rest stay at rest.
What is Newton's First Law?
Weight is a measure of
What is gravitational force?
Riding a bike is an example of what type of friction?
What is rolling friction?
What is an unbalanced force?
What is, When two forces act on an object and cause the object to move.
What is inertia?
What is, An object's tendency to resist a change in motion?
This law states that for every force, there is an equal and opposite reaction.
What is Newton's Third Law?

What is fluid friction, or air resistance?
Tom pushes a cart to the left with a force of 300 N and John pushes a cart to the right with a force of 300 N. Is the cart balanced or unbalanced?
What is balanced?
When two forces act in the opposite direction, you ________ them. When two forces act in the same direction, you _________ them.
What is subtract, add them?
Bob throws a rock with a mass of 5 kg so hard it flies through his neighbor's window at 10 mph. What is the force of his throw? (Include units!)
What is 50 Newtons?
___________ does not change (unless you cut your arm off), but ___________ changes depending on location.
What is mass, weight?
Slipping on a puddle of oil is an example of which TWO types of friction?
Claire pushes the cart to the left with a force of 1000 N and Jami pushes the cart to the right with a force of 300 N. What is the net force?
What is 700 N to the left?
The more distance there is between objects, the less _______ is there? The more mass there is, the more ________ there is?
Explain why equal and opposite forces don't always cancel out (Newton's third law).
What are the two forces are acting on two different objects?
Explain the difference between mass and weight.
What is Mass is a measure of how much matter there is in an object, and measured in grams. Weight is a measure of gravitational force and measured in Newtons.
Why is friction important?
What is, Without friction we would constantly be sliding around and never stop. Friction allows us to sit and move as we please?

What is 30 N diagonal?
