Forces in action

12. Forces and kinematics

Forces connect with the kinematic equations because forces, we know, cause acceleration.

In particular, when a force on an object is unbalanced, that object accelerates.

It's Newton's second law of motion that tells us how an object accelerates under an unbalanced force.

This equation for acceleration can be used to calculate the acceleration of an object when its mass and the net force acting on it are known.

To solve motion problems involving forces:

1. Find net force (by combining vectors).
2. Calculate acceleration (using 2nd law).
3. Use kinematics equations.
