The ____________ of an object is the energy it has because of its motion
Kinetic Energy

What word means, "how fast an object moves in a given amount of time."
Speed
100
What is the main difference between Speed and Velocity?
Velocity has a direction with it
100
What three particles make up an atom?
Proton, Electron, and Neutrons

Define balance force -
When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces. Object does not move or is at a constant speed.

_________ is the energy that is stored in an object due to its position.
Potential Energy

What is the formula for Speed?
Distance/Time

What part of an atom has a negative charge and is found in the electron cloud?
Electrons

Define unbalanced force -
A force where two forces acting in opposing directions on a body, are not equal in magnitude and in size. The force causes the object to move
