RESULTANT FORCES

• Newton's Third Law-

  Whenever two objects interact, the forces they exert on each other are equal and opposite.
• The acceleration of an object can be calculated from the gradient of the velocity-time graph.
• The distance can be calculated from the area under a velocity-time graph.
• Newton's first law-

  An object at rest remains at rest, or if in motion, remains at motion at a constant velocity.
• Newton's second law-

  If the resultant force on an object is not zero, the object will accelerate on the direction of resultant force.
