A balanced force is two or more objects produce a net force of zero N.What is a balanced force?
A balanced force is two or more objects produce a net force of zero N.
100
What is gravity?
What is a force of connection between two objects depending on their mass.

A experiment about boiling water is being tested. What is the independent variable?
What is the water temperature.
200
What energy is being used when someone goes down a hill?
potential energy Energy is the ability to cause change
200
What is the difference between speed and velocity?
Speed is an object in motion, velocity is an objects motion in a direction.
200
When the net force is not 0 N , and the forces are unequal.What is an unbalanced force?
When the net force is not 0 N , and the forces are unequal.
200
What would happen to an object in orbit with no gravity
The object would have no forces acting on it at all.
200
The _____________ blank variable never changes.
What is dependent.
300
What has more energy a walking cheetah or a running cheetah?
Running cheetah, because it is moving faster
300
How is average speed calculated?
You have to divide the distance by the time.
300
Is the Net force a combination of forces?
Yes it involves directions and different speeds.
300
An object traveling around another object in space is in __________.
What is orbit.
400
If an item has a greater mass will it gain more kinetic energy?
Yes because more gravity is acting on it.
400
A vector is a quantity that has both size and direction.What is a vector?
A vector is a quantity that has both size and direction.
400
what is Newtons first law?
What is inertia.
400
How do round objects in space form?
The mass is large enough so that the objects all come together and make a sphere.
500
The objects mass and height above ground.What are the Two factors that determine an objects potential energy?
The objects mass and height above ground.
500
By comparing a reference point with your position.What information do you need you need to describe an objects location?
By comparing a reference point with your position.
500
What are the two main types of forces?
It is push and pull
500
The moon does not fall to Earth because of friction?
False, because the force is actually gravity.
