What is Newton's 1st Law of Motion?
An object at rest stays at rest and an object in motion stays in motion until acted upon by an unbalanced force.

What is force?

A push or pull

If 20N of force are pushing to the left and 20N of force are pushing to the right, which way will the box move?
Neither way. It is a balanced or net zero force.

Newton's first Law is also called?

Inertia


200
What is Newton's 3rd Law of Motion?
For every action there is an equal and opposite reaction.
200
What is inertia?
An object's tendency to resist a change in motion.
200
If someone is pushing with 50N of force to the right and the other person is pushing with 10N of force to the left, which way will the box go?
To the right, because there is more force pushing that way.

What is the formula for the 2nd Law?

Force=mass*acceleration

What is Newton's 2nd Law of Motion?

Deals with force, mass, and acceleration

300
What is friction?
A force that acts against moving objects.

If Spongebob was pushing a crabby patty to the left with 25N and plankton was pushing it to the right with 15N, which way would it go and why?

To the left, because Spongebob is bigger and stronger than plankton.

What happens to the speed of a little brother, if it is required to pull a big brother?

It goes slower.

300

What is an unbalanced force?

Where the net force is greater than 0.

400

Newton's 1st Law
400

What is gravity?

The force of attraction that exists between any two objects that have mass (usually a downward pull)

400
If two people are pushing a box to the right and each person is putting forth 20N of force. Which way will the box move and with how much force will it be moving?
To the right with 40N worth of force.

What happens to the speed of a big brother, if it only has to pull a little brother?

It goes faster.

You give a shopping cart a shove down the aisle. If you applied a force of 50 N to cause the cart to accelerate at a rate of 2 m/s2, what must be the mass of the cart?

25kg

500
A rocket ship blasting into space is an example of which law of motion?
Newton's 3rd Law of Motion
500

What are balanced forces?

When the net force equals 0
