Question | Answer |
What is the formula for Elastic Potential energy? | mass times gravity times height |
What is the formula for kinetic energy? | k=1/2 mv^2 |
What is the formula for speed? | distance divided by time |
What is the formula for distance? | velocity times speed |
What is a contact force? | Contact must have force implied to work |
What is a non contact force? | Non contact do not require any physical force between the two objects |
How can an object move when something is touching it? | Apply force onto the object |
Name two common reference points. | Tree , building |
What is defined when an objects distance from another object is changing? | Motion |
What is an example of a graph with constant speed? | Goes in a straight line from the bottom left to the top right |
Define force. | In physical science, a push or a pull |
The rate at which an object is moving at a given instant is? | Instantaneous speed |
A newton is used to measureā¦.? | Force |
What type of force allows objects to move? | Unbalanced |
What is the net force if a force of 12 N is applied to a box on the right and 12 N to the left? | 0 Net force |
If a rubber band has a stretch of 0.1 meters past equilibrium and a spring constant of 40, determine the elastic PE: | Gravity times mass times height 0.5 times 40 times (0.1)^2 = 20 times 0.1 = 0.2 Joules |
Someone weighs 100kg and is running around a track, he can run 3m/s. What is hes kinetic energy? | 1/2 mass times speed = 1/2 x 100kg x (3m/s)^2= 450 Joules |
How does mass and distance affect gravity? | The more mass means gravity will happen faster. And vice versa. The more motion/distance means the more gravity will slow you down if a lot of mass. And vice versa. |
