2. Mathematical Review
The following formulas are used to help us solve Physics problems:
F = ma ( Newton’s Second Law)
PE = mgh ( Potential formula)
KE = ½ mv2 ( Kinetic energy)
W = f xd ( Work)
Vavg = d/t ( Velocity)
Aavg = v/t (Acceleration)

3. Math Review
Suppose you had a problem in physics and you had to solve for mass in the potential energy formula. ( PE = mgh)
Step 1 ….. PE = mgh
Step 2 ….. Rewrite the formula: mgh = PE
Step 3 …. Divide both sides by gh
Step 4 …. m = PE/gh

4. Math Review
Suppose you wanted to solve for acceleration in the formula (F = ma):
Step 1 …. Write the formula: F = ma
Step 2 …. Rewrite the formula as: ma = F
Step 3 …. Divide both sides by a:
Step 4 …. After dividing, then the formula is m = F/a

6. What is Physics?
Many people consider physics as a science that evolves many formulas.
Physics is the study of the physical world.
There would be no inventions of appliances, tools and other things without physics.
