Balanced and unbalanced forces
What this topic asks you to be able to do
- Identify and use the various kinds of force, including friction, drag, air resistance, contact force, weight (gravitational force), tension (elastic force), thrust (driving force), magnetic force and electrostatic force
- State that a force can alter how an object moves by altering its direction or its speed
- Work out the resultant when two or more forces lie along one straight line
- State from memory the equation “resultant force = mass × acceleration” and use it
