... follow that block B has twice the acceleration of block A? Justify your answer using Newton's second law. C.3 When a brick rests on a flat, stationary, horizontal table, there is an upward normal force on it from the table. Explain why the brick does not accelerate upward in response to this force. ...

... The Shock Drop is an example of vertical free fall, followed by a sharp deceleration. Whether we are jumping on the trampoline or dropping in the Shock Drop the physics is the same – we are in free fall. That is, the only force acting on us is gravity (apart from our possibly clutching at the safety ...

Laws of Motion PPT
... If the resultant force acting on an object is not zero, all the forces are said to be unbalanced. This forms the basis of Newton’s second law of motion, which states: If the forces on an object are unbalanced, two things about the object can change: the speed of the object may change – it may eith ...
