• Velocity

• Acceleration

• Speed

What is the formula for Acceleration?

• f = ma

• a = f/m

• m = fa

What formula will be used for the question asked above?

• a = f/m

• a = m/f

• f = ma

work is only done when....

• object move in the direction of the applied force

• object does not move

• as long as the object moves

Unbalanced forces...

• change the speed and direction of the object

• object does not move, stays at rest

• equal and opposite forces

balanced forces

• equal and opposite force and stays at rest

• object is in motion

• forces are not equal
