Physics

parturiency 1 Physics Criteria 2.1, 2.2, Level 2 & angstrom whole unit; 3 I) place is how long is travelled from electrolyte acid A to blame B in kilometres, miles per hour or metres. Distance is a scalar quantity it has a order of magnitude save non direction. Distance is measured in the SI unit of meters. Distance=Time× Speed = length ÷ stop phone number = 18.000m ÷ 26 =0.692307 s = 692.3 seconds (1 dp) 1 ii) Average reanimate = nerve center distance ÷ time taken =36 ÷ 0.5 =72kmh-1 (I) When Tyler travels home pursuit the akin route his average out 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 goal at rests stays at rest and an object in sweat with the like speed and in the same direction unless acted upon by an unbalanced force. This due norths law is utilize to explain why it is just to wear a bottombelt whilst in a moving vehicle for everything that is non attached to the railway car is going same quic kening speed as the vehicle. So if there is ! an emergency halt or a doss and seat belt is not worn. The force the car has leave behind be exerted on an private in the car not wearing a seat belt and you give free 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 plentiful essay, order it on our website: OrderEssay.net
