MOTION

• What is motion?• Any physical movement or change in position or place

• What is speed?• The rate at which something moves\

Speed/velocity

=

𝑑𝑡 d = distance; t = time

• What is velocity?• Speed with a direction

• Ex: 50 mph north on I-75

• What is acceleration?• The increase or decrease in velocity over a certain period of time

Acceleration

=

𝑉𝑓 −𝑉𝑖𝑡 𝑉𝑓 = final velocity; 𝑉𝑖 = initial velocity; t = time

• What is energy?• how much work an object or system can do on some other object

or system

• Kinetic Energy

Kinetic energy = 12𝑚𝑣2 m = mass; v = velocity

• Gravitational Potential Energy

Gravitational potential energy = 𝑚𝑔ℎ m= mass of the object (in kilograms) g = force of gravity (g = 9.8 Newton/1kilogram) h = height of the object (in meters)
