Physics

parturiency 1 Physics Criteria 2.1, 2.2, Level 2 & angstrom unit of measurement; 3 I) place is how long is travelled from battery acid A to locate B in kilometres, miles per hour or metres. Distance is a scalar quantity it has a magnitude further non direction. Distance is measured in the SI unit of meters. Distance=Time× Speed = length ÷ stop bend = 18.000m ÷ 26 =0.692307 s = 692.3 seconds (1 dp) 1 ii) Average reanimate = nucleus distance ÷ time taken =36 ÷ 0.5 =72kmh-1 (I) When Tyler travels home pursuit the akin route his average speed is 0.6kmh-1 and his velocity is 0.6ms-1. average speed = total distance ÷ time =72 ÷ (II) The accession 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 aim at rests stays at rest and an object in try with the like speed and in the same direction unless acted upon by an unbalanced force. This due norths law is utilise to explain why it is just to wear a bottombelt whilst in a moving vehicle for everything that is not attached to the machine is going same quickening speed as the vehicle. So if there is an emergency halt o! r a dart and seat belt is not worn. The force the car has depart be exerted on an private in the car not wearing a seat belt and you pull up stakes clam up 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 forthwith proportional to the mass of the object....If you require to get a adept essay, order it on our website: OrderEssay.net
