Balancing Act
If you want to move an object, you must apply this type of force.
The sum of all the forces on an object
What is net force
The unit of measure for force
What is a Newton
This is the transfer of energy taking place when a rollercoaster goes up, then down a hill.
What is potential to kinetic energy?
These are the two main types of energy.
What are potential and kinetic energy?
Complete the phrase: An object at rest will stay at rest unless this occurs.
What is is acted upon by an unbalanced force?
A dog and cat are playing tug of war. The dog pulls with 30 N, and the cat pulls with 50 N in the opposite direction. What is the net force?
What is 20N?
The unit of measure for energy.
What is Joules?
An object placed on a higher shelf will have more of this energy than before.
What is potential energy?
What is chemical?
Two boys push to the left. They both push with a force of 25 N. Another boy pushes to the right with a force of 50 N. What is the net force and direction?
0N, they won't move.
This is an opposing force that slows or stops an object.
What is friction?
This is speed that gravity pulls you down at.
What is 9.8m/s?
Name all FOUR types of friction.
What are static, rolling, fluid, and sliding?
A student sitting is an example of this type of force.
What is a balanced force?
Drew pushes a car to the left with a force of 60 N. Danny helps Drew, and pushes with a force of 54 N. What is the net force and direction?
What is 114 N to the left?
This states that energy is neither created nor destroyed.
What is the Law of Conservation?
This is the energy transfer taking place when a stereo turns on.
What is electrical to radiant?
Name two types of kinetic energy.
What are light (radiant), sound, thermal, and electrical?
This is how you know an object is moving.
What is change in its position?
A girl is walking her dog. She is pulling with a force of 12 N. The net force is 24 N. What force is the dog pulling with?
What is 36 N?
This is the sum of potential and kinetic energy.
What is mechanical energy?
This is the formula for kinetic energy.
What is 1/2 mass times velocity squared?
Name three types of Potential Energy.
What are Elastic, Gravitational, Chemical, Nuclear?
