Forces and Energy
Affect of Forces of Motion and Energy affecting Motion
Question | Answer |
---|---|
Force is | Push or pull of an object changing its motion |
Requires a large force to move it | Bowling ball |
Gravity | Force pulling two objects toward one another or the center of the earth |
On earth gravity pulls you into which direction | Center of the earth |
Inertia | An object staying in motion or at rest |
A toy car in front of you with no movement is | Inertia |
Friction | Rubbing against each other, and it slowing down things in motion |
A ball slowing down the grass is caused by | Friction |
Two results force can have on motion is | Can cause objects start moving, speed up, slow down or change directions |
A ball continuing to move without stopping | Does not have friction |
A roller coaster is being pushed down because of | Gravity |
Energy | Ability to do work |
Potential Energy | Energy an object has because of its position |
When you are at the top of a slide waiting to come down you have what type of energy | Potential Energy |
When you kick a ball, you give it | Kinetic Energy |
A bicycle moving when you pedal it is | Mechanical Energy |
Kinetic Energy | Energy of motion |
Mechanical Energy | Energy it has because it can move or of its motion |
A toy using a battery is powered by | Chemical Energy |
An object can have two types of energy such as | Potential and Kinetic Energy |
Energy stored in a battery | Chemical Energy |
Three forms of energy are | Mechanical, Chemical, Electrical |
