Study the motion map shown. Some of the vectors have been circled. What do the circled vectors represent? distance speed velocity acceleration

(e) The acceleration of the apple is 9.8 mathrm(~m) / mathrm(s)^2 The velocity of the apple changes from 0 to 4.9 mathrm(~m) / mathrm(s) Calculate the time taken for the apple to fall to the ground. Use the equation: [ (1+4.4)/(9.8)=0,5 ]

When the apple is ripe it falls from the tree and accelerates towards the ground. (d) Why does the apple accelerate? Tick (surd ) one box. The resultant force on the apple is downwards. square The resultant force on the apple is upwards. square The resultant force on the apple is zero. square

(e) Which two statements are correct about the particles when a liquid turns into a gas? Tick two boxes. Particles are bigger Particles are lighter Particles have more chemical energy Particles have more kinetic energy Particles move faster
