What does Newton's 1st law state?
An object at rest will stay at rest and an object in motion will stay in motion unless acted on by an outside force.
101
What is one of the two formulas for Newton's 2nd Law?
Force = Mass x Acceleration (F = ma)
Acceleration = Force ÷ Mass (a = f/m)
101
What does Newton’s third law state?
For every action, there is an equal and opposite reaction.

What are two ways that an object can accelerate?
Changing speed
Changing direction

Is the following demonstrating balanced or unbalanced forces?
A young boy pushing a shopping cart.
Yes - the shopping cart is moving

How many sides are on a heptagon?
7 sides
300
What is inertia?
The tendency of an object to resist a change in motion.
300
What is the ACCELERATION?
0.2 m/s2
300
Is the diagram of action/reaction forces correct? Why or why not?
<---- Action
<---- Reaction
Not correct - The reaction force should be pointing in the opposite direction.
It should be:
<---- Action
-----> Reaction
300
Is the object accelerating?
A car traveling at a constant speed going around a corner.
Yes - changing direction
300
The sum of all forces acting on an object is called:
Net Force

In Celsius, what is the freezing point of water?
0 ℃
400
What does inertia depend on?
Mass: More mass = more inertia

400
What two things does momentum depend on?
Mass and Velocity
400
Is the object accelerating?

Newton’s 1st law says that an object in motion will stay in motion.
If I roll a basketball across the floor, it stops at some point.
Why does it stop? Give one reason.
An unbalanced force acts on it (friction)

Mr. DeCounter is pushing a box across the floor. The box has a mass of 10 kg and is accelerating at a rate of 3 m/s2. How much force is Mr. DeCounter pushing the box with?
30 Newtons

How does the mass of an object or the velocity of an object determine the momentum of an object?
The more mass or velocity an object has, the more momentum it has.
