A push or a pull
Force
The law that states: Force is equal to the mass times the acceleration
Newton's Second Law
A car speeding down a highway
Draw a Picture.
The car exerts a force on the highway and the highway exerts an equal and opposite force on on the car.
According to Newton's Second Law, an object that gets pushed or pulled with a specific force will accelerate. If we apply the same force to a more massive object, what happens to the acceleration?
The acceleration decreases.
Newton's First Law is also called the Law of...
Inertia
A statement answering a question or solving a problem
Claim
You would use this law to explain why things continue to move in a straight line even when no forces are acting on them in the direction of their motion.
Newton's First Law
The Moon exerts a force on the Earth that is ________ to the force the Earth exerts on the moon.
Equal to
When the applied force increases what happens to the resulting acceleration?
The Acceleration Increases
Objects with greater _____ also have greater inertia
mass
A quantity that has both a magnitude and a direction
Vector
This law states: For every action there is an equal and opposite reaction.
Newton's Third Law
When a heavy football player and a light one run into each other, who exerts more force?
They are equal
I would do this to get something to accelerate faster.
Apply a larger force
These kinds of objects have inertia
all objects with mass
A list of things that are interacting
System
This Law states that: "Objects in motion tend to stay in motion, and objects at rest tend to stay at rest unless acted on by an unbalanced force"
Newton's First Law
When holding an apple above one's head, these are the equal and opposite forces.
Force up from the hand on the apple, force down from the apple on the hand
When something has units of m/s/s or m/s^2, it is known as this.
Acceleration
All of the arrows are balanced. Left and right arrows are balanced, up and down arrows are balanced.
The distance an object travels per unit of time
Speed
You would use this law to calculate how much an object would accelerate if you knew the objects mass and the force applied to the object.
Newton's Second Law
A bus hits a bug and the bug splatters on the windshield, which force is greater?
They are equal
Suppose two carts, one twice as massive as the other, fly apart when the compressed spring that joins them is released. How fast does the heavier cart roll compared with the lighter cart?
Twice as fast
The same
Half as fast
Half as fast
Friction refers to this direction in comparison to the direction of motion.
against the direction of motion.
