Force
What is force?
Force is any push or pull.
What is motion?
Motion is the action of changing location or position .k
What is friction?
A force that acts when 2 surfaces rub together.
What is gravity?
A force that is a pull and keeps things on Earth grounded.
What is a frame of reference?
Object that don’t seem to move
What is a Newton a measure of?
The force needed to do something.
What is work?
The ability to move something.
What is friction the resistance of?
Motion.
What type of energy does a wrecking ball have when it is smashing a building?
Kinetic energy
What are kinetic and potential energy?
Kinetic energy is the energy that an object has in motion, and potential energy is stored energy.
Pushing and pulling can change what?
It can change the position and motion

Yes
Why is there less friction on a marble floor?
Because the floor is smoother
Are mass and weight the same?
No
What tool is used to measure force?
A spring scale
Name four forces.
Gravity, friction, push, pull
What are relative motion and frame of reference?
The change in one object’s position compared to another object’s position, and the object’s that don’t $eem to move.
Is there any place/object on Earth with no friction?
No
who made the spring scale?
Issac Newton
What happens to the gravity of an object when you double the object’s mass?
The gravity doubles on that object

Bonus with 100 extra points I s which has more mass?
A regular ball.
