List three contact forces and three non-contact forces.
Contact: applied, friction, air resistance, buoyancy, elastic, tension.
Non-contact: gravity, magnetic, static electricity

What can increase an object's gravity?
What can decrease an object's gravitational pull on anther object?
Objects with more mass have more gravity.
As distance increases, the force of gravity decreases.

How would you describe the forces in this image?
They are balanced resulting in no movement. 0 net force
300
Explain the difference between balanced and unbalanced forces.
Balanced forces are those that are equal in magnitude but opposite in direction. The net force of balanced forces is zero. Objects acted upon by balanced forces stay at rest or move at a constant velocity. Unbalanced forces are forces that are not equal in magnitude and may or may not act in the same direction.

Define gravity
An attractive force between any two objects that have mass

Explain why an object would take longer to slide down a surface of sandpaper compared to a surface of smooth, waxed wood.
Smooth, waxed wood has less friction.

Name 2 types of frictional forces
Static friction, sliding friction or rolling friction

Recall Newton's First Law of Motion
an object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Would it be easier for a rocket to take off from the Earth or the moon? Justify your anser.
The moon because it has less mass. Therefore, it has a weaker gravitational field strength.
