This law states an object will keep doing what it is doing if the forces acting on the object balanced.
What is Newton's First Law?
100
The acceleration of an object is related to the net force acting on it and the object's mass.
What is Newtons Second Law of Motion?
100
This is the law that states for every action, there is a reaction of equal magnetude, but opposite in direction.
What is Newtons third Law of Motion?
100
When an object's speed or direction changes, the object undergoes this?
What is acceleration?
100
An example of a contact force is.
A. Friction
B. Potato
C. Mass
D. Gravity
What is A. friction?
200
An objects resistance to a change in its motion.
What is Inertia?
200
Many forces can act on an object at the same time. When you add up all the forces you get?
What is Net force?
200
What is an example of the Third Law?
A. Sheering a sheep
B. Hammering a nail
C. Opening a can of coke
D. All of the above
What is B. Hammering a nail
200
A push or pull that can cause the motion of an object to change.
What is force?
200
A force that acts on an object from a distance.
What is non contact force?
300
If you hit a home run in space, what would happen?
There is no gravity, therefore the ball wouldn't go as far and it wouldn't go as fast.
300
When you are resting, what force is being acted on?
A. Acceleration
B. Motion force
C. Nothing
D. Kinetic energy
What is C. Nothing.
300
What do equal and opposite forces act on?
What is different objects with greatly different masses?
300
If it touches an object it changes its speed or direction.
What is contact force?
300
Give an example of a situation in which you apply a force to somehting and it does the following.
Goes faster.
What is when you're riding a bike.
400
Suppose you're playing baseball and you hit a home run. These forces slow down the ball while it is in motion.
A. Resistance from the air and friction
B. Acceleration
C. Kinetic energy
D.Inertia
A. Resistance from the air and friction
400
When you are accelerating what two forces are acting on eachother?
What is pushing and friction?
400
True or false?
If the forces are equal and opposite, they don't cancle eachother out.
What is true, If the forces are equal and opposite, they don't cancle eachother out.
400
The force exerted by an object to balance an outside force acting on it.
What is normal force?
400
Give an example of a situation in which you apply a force to somehting and it does the following.
Goes slower.
What is when you hit the breaks at a slow pace on a bike?
500
Gabe kicked a soccer ball across a field. The ball rolled for a while but eventually stopped. If Newton's first law is true, it seems that the ball Gabe kicked should continue rolling forever. Why is this?
An object will keep doing what it is doing if the forces acting on it are balanced.

Sharon cruises east at 7 m/s. She uses her brakes and comes to a gentle stop. As Sharon slows, how does the direction of the net force compare to that of her motion?
A. 7 m/s south
B. 7 m/s west
C. 5 m/s west
D. None of the above
What is A. 7 m/s south?

Think back to the story of Alicia and the soccer ball. Using Newtons Third Law of Motion, explain how she could kick the ball into the goal.
What is by using her feet to kick the ball and give it energy so it can go into the goal?
500
Is a force that pulls two objects with mass towards eachother.
What is gravity?
500
Give an example of a situation in which you apply a force to somehting and it does the following.
Change direction.
What is slaming the breaks on a bike and going backwards?
