|---|---|---|---|---|
|
What is FORCE
This word is defined as a push or a pull
|
What is INERTIA
Newtons first law of motion is also known as
|
What is F=MA
What is the formula that describes Newton's 2nd law of motion?
|
What is Action and reaction (for every action there is an opposite and equal reaction)
Newton's 3rd law of motion is also known as
|
What is NEWTON'S 1ST LAW OF MOTION
When you are standing up in a subway
train, and the train suddenly stops, your body continues to go forward. |
|
What is NEWTONS (N)
This is the unit of force
|
What is AN OBJECT IN MOTION WILL REMAIN IN MOTION AND AN OBJECT AT REST WILL REMAIN AT REST UNLESS A FORCE ACTS UPON IT.
Newton's first law of motion states that
|
What is ACCELERATION
The rate at which an object changes its velocity is known as
|
What is TRUE- More friction causes an object to slow down
True or False: The more friction the slower an object will go
|
What is NEWTON'S 2ND LAW OF MOTION
An ice skater pushes harder with his leg muscles, he begins to move faster
|
|
What is NET FORCES
All of the forces acting on an object are called
|
What is ZERO (0)
If 2 people are pulling on a rope with a force of 200N, what is the net force?
|
What is 45N
An object with a mass of 5kg that accelerates at 9m/s2 when an unknown force is applied to it. What is the amount of force?
|
What is ACTION=PULLING WATER BACKWARD, REACTION=MOVING FORWARD
If you are swimming, what is the action and what is the reaction?
|
What is NEWTON'S 3RD LAW OF MOTION
When you use poles to push you forward when you ski
|
|
What is REFERENCE POINT
You can use this to help you notice if you or something has moved
|
What is 1000N
You are pushing a cabinet with a force of 500N and your friend is pulling the cabinet in the same direction with a force of 500N, what is the Net force?
|
What is .25grams(g)
An object accelerates at 20m/s2 when a force of 5N is applied to it. What is the mass of the object?
|
What is FALSE- They always act in pairs
True or False: All forces act individually on one another 1 at a time.
|
What is NEWTON'S 2ND LAW OF MOTION
A baseball hit with a wooden bat flies further than a baseball hit with a plastic bat
|
|
What is INERTIA
The tendency of an object to resist any change in motion is known as
|
What is 350N
You are pulling with a force of 800N and your friend is pulling in the opposite direction with a force of 450N what is the net force?
|
What is 3m/s2
An object with a mass of 8g has a force of 24 newtons applied to it, what is resulting acceleration of the object?
|
What is FALSE! -According to Newton's first law, A body continues in its state of rest or motion unless an external force is acted on it. So the velocity of the body can not slow down without external force.
True or False: An object initially moving at a constant velocity will slow down unless net force is applied.
|
What is NEWTON'S 3RD LAW OF MOTION
A bookshelf stays in place because of this law of motion
