What is an applied force?
When one object applies force to another object.
100
When an object is pushed or pulled by another object, what kind of force is this?
applied force
100
Which of these pull forces is weaker?
A kid pulling a wagon.
A truck pulling a trailer.
A kid pulling a wagon.
100
If I push an object on its left side, which direction will it move?
It will move to the right!
100
True or false: every object is capable of having elastic force.
False. The object needs to be stretchy and able to return to its original shape.
200
What is inertia?
An object at motion stays in motion. An object at rest stays at rest. It is related to Isaac Newton's first law of motion.
200
When an object is pushed from two or more sides, what kind of force is this?
Squeezing force
200
Which force is stronger?
A 3 year old kicking a soccer ball as hard as he can.
Mr.M kicking a soccer ball as hard as he can?
Mr.M kicking a soccer ball as hard as he can.
200
If I pull an object from the left, which direction will it go in?
It will go to the left.
200
If I throw a ball to my friend, am I using a push force? Or a pull force?
Push force
300
What is elastic force?
When an elastic object is stretched and released, the force that comes when the object is released is called elastic force.
300
When an object is pulled from two or more sides, what kind of force is this?
Stretching force
300
Which of the following would require a strong force?
Lifting a box full of feathers.
Lifting a box full of pencils.
Lifting a box full of pencils.
300
If I push an object from the bottom, which direction will it go in?
It will go up!
300
I throw a ball onto the ground and it bounces back up to my hand. Which two forces are being demonstrated here?
Applied force (can also accept contact force or push force) and elastic force.
400
What is friction?
When an object is in motion, friction is the opposite force that slows it down until it eventually stops.
400
When a object is pushed from the top, what kind of force is this?
Squeezing (or crushing) force

Billy is able to push 125 lbs on a bench press. Johnny can push 115 lbs on a bench press. Which of the two boys is weaker?
Johnny is weaker.
400
If I push an object on it's left and right side, which direction will it go in?
It will not go in any direction, but the object will experience a squeezing force.
400
Two forces are closely related to each other. An example of one force is hanging something from a string. The other force involves pulling an object from two or more sides. What are these two forces.
Tension and stretching.

Who is Isaac Newton?
He was a famous British scientist who is seen as the "Father of Physics".

When you hang a weight from a string, what kind of force do we see in the string?
Tension force
