Kinetic, Mass, and Speed Relationships & Forms
Science Vocabulary Word | Definition |
---|---|
kinetic energy | Energy an object has due to motion. |
Joules | The SI unit of work or energy. |
acceleration | The rate at which velocity changes. |
deceleration | A reduction "slowing down" in speed or rate. |
velocity | The speed and direction of an object. |
mass | The amount of matter in an object. |
motion energy | The energy of an object in motion. Related to kinetic energy. |
thermometer | Tool used to measure the temperature of an object. |
speed | The distance an object travels per unit time. Example (60 miles/hour) |
proportional | A relationship or comparison between two numbers or variables. |
momentum | The measurement of mass in motion. |
mechanical energy | The energy of an object due to its motion and its position. |
Sound energy | The energy we can hear and moves through the air and other objects in the form of waves. |
Light energy | A form of electromagnetic energy/radiation that can be seen and travels in waves. |
Heat energy | Also callled thermal energy and is due to the movement of molecules. This kind of energy can be transferred from one object to another. |
