Shafter
Mrs. Shafter's Motion Vocabulary
| Question | Answer |
|---|---|
| The resistance of an object to a change in the speed or the direction of its motion. | inertia |
| A change in position over time. | motion |
| A push or a pull. Something that changes the motion of an object. | force |
| A measure of how fast something moves through a particular distance over a definite time period. | speed |
| The rate at which velocity changes over time. | acceleration |
| A speed in a specific direction. | velocity |
| The use of force to move an object over time. | work |
| The rate at which work is done. | power |
| Law of inertia. | Newton's First Law |
| Force equals mass times acceleration. | Newton's Second Law |
| Action reaction | Newton's Thrid Law |
| The force that objects exert on each other because of their mass. | gravity |
| This is a measure of how much matter an object contains. | mass |
| Power can be calculated from energy and______. | time |
| This divided by time equals speed. | distance |
| This is the speed that you are currently traveling at the moment. | instantaneous |
| A greater distance results in a _________ gravitational force. | smaller |
| A greater mass results in a _________ gravitational force. | greater |
| Positive acceleration occurs when the speed of the object __________. | increases |
| When the speed of the object decreases it is called ___________ acceleration. | negative |
| Velocity is different from speed in that it must also contain ______________. | direction |
| Acceleration is a __________ in velocity over time. | change |
| This is subject to forces acting on it. | matter |
| The overall force acting on an object when all the forces are combined is called the ______. | net force |
| Only an__________ force can cause motion in an object. | unbalanced |
| This is used to measure distance in metrics. | meter |
| This is a type of energy resource that cannot be replaced in a short period of time. | non-renewable |
| These natural resources come from the compacted remains of plants and animals. | fossil fuels |
| The energy that comes from the chemical composition or position of matter. | potential |
| This is the energy of motion. | kinetic |
| As the frequency of a wave increases so does its ___________. | energy |
| As the wavelength increases its energy ___________. | decreases |
| These EM waves have the greatest energy. | gamma rays |
| This is the part of the experiment that stays the same every time the lab is done. | constant |
| This is the main source of energy for our planet. | sun |
| This piece of lab equipment would be used to measure thermal energy. | thermometer |
| This type of energy is found in food. | chemical |
| Wind, solar and water are types of this form of energy. | renewable |
| This is how the Sun's energy travels to Earth. | radiation |
