1. Newton’s Second Law
F=ma

2. Newton's Second Law of Motion:
The acceleration of an object is directly proportional to the net force applied on it and inversely proportional to its mass.
F = ma

3. Newton’s Second Law
Huh? What does that mean? Let’s rewrite it so that it’s easier to understand:

4. Newtons!
Acceleration is always in the same direction as the force causing it….which means force is a vector. The unit for force is Newton’s (N)

5. Newton’s Second Law states:
When a force acts on an object, the object will accelerate in the direction of the force.
If there is no force, there is no acceleration.

6. Can we explain the diagram?

7. F=ma Grab your formula sheet!
Joe Smoe pushes his car out of the ditch. He is pushing with an acceleration of .05m/s/s and the car weighs 1000kg. How much force is he using?
