Force
What is... Force!
Force is a push or a pull.
What does... (N) stand for!
(N) stands for Newtons.
When two people push an object in the same direction, how would you find the net force?
You would add the two forces together.
Is gravitational force greater or weaker when objects are farther apart?
When objects are farther apart the gravitational force is weaker.
Is holding a ball in front of a cliff kinetic or potential energy.
Potential!
What is... friction!
Friction is a force that opposes motion, or in other words, slows things down.
What is... Newton's first name!
Isaac!
If two people push an object in the opposite direction how would you find the net force?
You would subtract the two forces.
When the mass of an object is decreasing the gravitational force is doing what?
The gravitational force is decreasing.
How do you find net force?
By adding or subtracting the Newtons of force on each side.
What is... Magnetism!
Magnetism is when a magnetic metal object attracts another metal object and they attach to each other.
What is... Newton's first law!
"An object at rest remains at rest, and an object in motion remains in motion at constant speed."
If Ian pushes a box with 20N to the right and Katelyn pushes the same box with 40N in the opposite direction, what is the net force?
20N to the left.
If objects A are together and big and objects B are apart and small, which objects have the most gravitational mass?
Objects A have the most gravitational force.
What is... Applied force?
Applied force opposes friction, it is when something pulls or push's something making it move.
What is... Normal force!
Normal force is a force that opposes gravity,in other words, it keeps an object from falling through whatever it is placed on.
What is... Newton's second law!
(This one is kind of hard.)
"the affect of net force and mass upon the acceleration of an object."
If sally pushes a box with 2N and Brad pushes the same box with 3N in the same direction, what is the net force?
The net force is 5N.
When the distance increases what does the gravitational force do?
The gravitational force decreases.
What is... potential energy?
It is when an object has a lot of energy stored inside of it because it is not moving.
What is... Gravitational force!
Gravitational force pulls things (with large mass and are close to each other) together.
What is... Newton's third law!
"Every action has an equal and opposite reaction."
If a girl is pushing a box to the left with 20N and a boy is pushing the box to the right with 30N which way does the box go?
The box will move to the right with 10N.
An apple falls into a pool and then floats on the water in the pool and then it rots, what did gravity do in the scenario?
Gravity made the apple fall.
What is... Kinetic energy?
Kinetic energy is the energy of something in motion.
