If the road is icy, describe and explain what change there would be, if any, to the thinking distance and braking distance Click the card to flip it 👆 thinking distance -no change;depends on speed/ driver / reaction (time)Braking distance- Increase as there is less friction/grip Click...
Free body diagrams show all the forces acting on an object. For example, a skydiver's weight acts on him by pulling him down towards the ground- air resistance (drag) acts upon him, in the opposite direction to his motion. What do the sizes of the arrows show?
Physics Revision – MOTION (HT) A 0.5 kg trolley is pushed at a velocity of 1.2 m/s into a stationary trolley with a mass of 1.5 kg. The two trolleys stick to each other after the impact. Calculate: The momentum of the 0.5 kg trolley before the collision The velocity of the two tro...
Newton’s 3rd law of Motion If object A EXERTS A FORCE on object B….. Then object B exerts the EXACT OPPOSITE FORCE on object A …OR… ‘for every action there is an equal & opposite reaction’ Questions on:- Force, mass and acceleration A force of 3000N acts on a motor bike to...
