resultant force

• what is a driving force?

  the force that makes it move - this force pushes the car forward because there is friction between the ground and the tyre of each drive wheel.
• what is the formula for weight, mass and gfs?

  W = mg
• weight and mass of an object are directly proportional
• forces are vector quantities as they use both magnitude and direction
• how do you find resultant force?

  driving force - total force acting against driving force
• resultant force must be 0 for equilibrium
• resultant force is a single force that could be drawn to represent the combined effect of all the forces acting on a body
