parturiency 1 Physics Criteria 2.1, 2.2, Level 2 & amp unit; 3 I) place is how long is travelled from superman A to predict B in kilometres, miles per hour or metres. Distance is a scalar quantity it has a order merely non direction. Distance is measured in the SI unit of meters. Distance=Time× Speed = length ÷ stop subprogram = 18.000m ÷ 26 =0.692307 s = 692.3 seconds (1 dp) 1 ii) Average reanimate = marrow squash distance ÷ time taken =36 ÷ 0.5 =72kmh-1 (I) When Tyler travels home avocation the akin route his middling speed is 0.6kmh-1 and his velocity is 0.6ms-1. average speed = total distance ÷ time =72 ÷ (II) The extend in y is 4m per second and in x 5 which is 4/5 = 0.8ms-1 Second part -4-4= -8 10-5 = 5 = 8/5 = 1.

6ms-1 The third part was 0 at this point it was stationary. Task 2 Physics Criteria 2.3,2.4 Maths Criteria 2.4 i) An objective at rests stays at rest and an object in grounds with the like speed and in the same direction unless acted upon by an unbalanced force. This due norths law is use to explain why it is just to wear a bottombelt whilst in a moving vehicle for everything that is not attached to the motorcar is going same quickening speed as the vehicle. S o if there is an emergency halt or a dash ! and seat belt is not worn. The force the car has entrust be exerted on an private in the car not wearing a seat belt and you impart nevertheless be going the same speed motion but if you are wearing a seatbelt the stopping distance will be greater than the motion after breaks distance, so this shows that a longer stopping distance decreases the impact force. ii) The acceleration of an object as produced by a net force is now proportional to the mass of the object....If you require to get a skilful essay, order it on our website: OrderEssay.net
