Part 2 of Basic Physics

What is Potential Energy?

“Stored Energy” that an object has due to its position

What is Gravitational Potential Energy?

Potential Energy that is related to moving objects in a Gravitational Field

What is Chemical Potential Energy?

the stored energy in Chemical Bonds

What is a Chemical Bond?

the force of attraction between atoms that holds them together to form molecules

What is a Molecule?

a group of two or more atoms that are held together by Chemical Bonds

What is Kinetic Energy?

the energy an object has because it’s moving

What does Kinetic Energy Depend on?

Speed and Mass

What is Momentum?

the amount of motion an object has

What does Momentum Depend on?

Mass and Velocity

What is Angular Motion?

the Circular motion of an object around a fixed point

What is an example of Angular Motion?

Turning your body without moving

What is Angular Motion measured in?

Degrees or Radians

What is Angular Velocity?

a measure of the Rate of Change in Angular Position

What is Angular Speed?

how fast something is rotating while standing still

What is another name for Angular Speed?

Idle Speed

How many Degrees does the Earth Rotate in a day?

360 Degrees

What is the Center of Mass?

the point in an object where all its mass is concentrated

What is another term of Center of Mass?

Center of Gravity

What is Angular Momentum?

the Product of an object’s moment of Inertia and its angular velocity

What is the Conservation of Angular Momentum?

in a closed system, angular momentum is neither created or destroyed

What is Tension?

A Pulling Force

What does “Proportional” mean?

being equal in size, amount, or strength, or having the same constant ratio
