Is the difference between balanced and an unbalanced force - give one example?
What is a balanced force has a net force of 0. Example is a book sitting on a shelf. Unbalanced forces change the motion of the object - ball bouncing

Newton's First Law states
What is an object in motion stays in motion and an object at rest stays at rest until acted upon by an unbalanced force.
200
Would a pea, marble, volleyball, or bowling ball have the most momentum? Why?
What is bowling ball because it has more mass.
200
What are the formulas for Acceleration and Mass?
A=f/m, M=f/a
200
What keeps the planets in their orbits?
What is gravitational pull
300
The primary reason for the 4 seasons.
What is the Earth's tilt of 23.5 (not just it's rotation.)
300
When an unbalanced force acts on an object, the force
What is changes the motion of the object.

Which of Newton's law is a skateboard moving forward when pushed by the rider?
Newton's Third Law
300
The head of a hammer is usually steel, which makes it heavy and gives it enough force for hammering the nails. What force does the head of the hammer have to resist?
What is the force of the nail pushing in the opposite direction
300
What 2 things determine how much gravitational pull an object has?
Mass and distance
400
Why does the tilt of the Earth on it's axis create the seasons?
What is the angle of the sunlight varies on different parts of Earth at different times. (Intensity)
400
In order to have an object move, there needs to be a net force of ____________, which means that the force is________
What is more than 0 and unbalanced.
400
The greater mass an object has, the greater force is needed for the object to____________
What is accelerate
400
How much force is necessary for an object with 300kg to accelerate at a rate of 4m/s2.
What is 1200N
400
What type of resistance keeps paper from dropping as quickly as other objects?
What is drag or air resistance
