Why do you move left when a car moves right?
Inertia
Gravity
Force
The First Law of Motion is also called what?
Acceleration
Velocity
Inertia
Force
Which of the following is the best way of stating Newton’s first law of motion?
Objects in space move randomly and unpredictably because no forces act on them.
Objects at rest don’t move unless an unbalanced force acts on them, and objects in motion don’t slow down, speed up, stop, or turn unless a force makes them do so.
Balanced forces cause an object to move, and unbalanced forces cause it to stop moving.
Once an object at rest begins to move, it will soon begin to slow down, turn, or stop.
Which of the following gives the definition of inertia?
a sudden shift in acceleration
the ability of objects to move in a smooth, curving path
the tendency of objects to resist a change in motion
a continuous downward force

4th
A rollercoaster heading down a hill is _____________.
at rest
slowing down
accelerating
velocity
A car turns right without slowing down. Is this an example of acceleration?
No, acceleration is the increase or decrease in speed.
Yes, because the car changed directions.
Yes, because the car increased it's speed.
No, because the car did not change directions.
Which of the following is an example of balancing forces?
A Book resting on the table.
A pencil is knocked off the desk.
Which of the following is an example of an unbalanced force?
A book resting on the table.
A pencil that is knocked to the ground.
What is Newton's 2nd Law?
For every action there is an equal and opposite reaction.
Acceleration depends on two variables, the mass of the object and the amount of force.
What is Newton's 3rd Law?
For every action there is an equal and opposite reaction.
Acceleration depends on two variables, the mass of the object and the amount of force.
Looking at the image. Decide if this is balanced or unbalanced.
Unbalanced
Balanced
What is the formula for the 2nd law of motion?
a=lw
F=m/a
F=ma
What is Newton's Second Law?
The law of Inertia
F= M X A
M= A X P
You should not speed in a car.
What is the unit called that measures force?
Isaac
Newton
Yee
