NEWTON LAWS OF MOTION STEPS:

1. Speed = distance ➗ time = d/t;   Acceleration = change in velocity/time = ▵v/t

2. If no force, then no change in velocity. (1st law)

3. If force, then force = mass✖️acceleration.   F = ma (2nd law)

4. For every force, there is an equal force in the opposite direction. (3rd law)

5. See force diagram steps below.

Force Diagram Steps:

  1. Sketch. Make clear and large enough. Write all info given to the side.

  2. Draw an arrow for each force.

  3. Label what each force is pushing on

  4. Write which force are equal by 3rd law.

  5. Write force = mass x acceleration for each force. (2nd law)

  6. Compare masses (using ⟨, ⟩)

  7. Compare accelerations (using ⟨, ⟩)
