1. Energy Basics

What is energy?

the capacity to do work

TRUE or FALSE? Energy can be converted to different forms.

TRUE

What are the 2 main components of Mechanical Energy?

kinetic and potential energy

YES or NO? Mechanical energy and kinetic energy are the same thing.

NO

What is kinetic energy (KE)?

the energy associated with motion

TRUE or FALSE? The greater the mass of a moving object, the greater the KE (kinetic energy)?

TRUE

TRUE or FALSE? The slower the speed of an object, the greater the KE (kinetic energy)?

FALSE

TRUE or FALSE? The faster the speed of an object, the greater the KE (kinetic energy)?

TRUE

What is the standard metric unit of energy?

joule

Can motion be ordered or disordered? YES or NO?

yes

What is disordered motion?

random movements of molecules in gas

What is kinetic energy that moves in a disordered motion called?

thermal energy

Does higher thermal energy mean that there will be a higher temperature? YES or NO?

yes

One of the components of mechanical energy is kinetic energy. What is the second?

potential energy

What is potential energy?

stored energy that can be converted into kinetic energy

Why aren't potential energy and kinetic energy the same thing?

kinetic energy requires an object to be moving/rotating
