Motion

Question 1

Distance,d

Answer 1

-How far one point is from another point (total ground travelled)

Question 2

Displacement,s

Answer 2

Distance with direction

Question 3

speed definition, formula and unit

Answer 3

Total distance travelled per unit of time
formula: speed = distance/time
Unit: m/s, ms^-1

Question 4

Velocity definition, formula and unit

Answer 4

speed with direction
formula: velocity = displacement/time
Unit: m/s (direction)

Question 5

Acceleration definition, formula and unit

Answer 5

change in velocity per unit of time
formula: a= (v-u)/t
v= final velocity, u = initial velocity
Unit: m/s2, ms^-2

Question 6

Kinematic equations :)

Answer 6

1. V = u + at - (s)
2. S = 1/2(u+v)t - (a)
3. S = ut + 1/2at^2 - (v)
4. V^2 = 2as + u^2 - (t)

Question 7

What affects terminal velocity

Answer 7

the lighter the object, the faster it reaches terminal velocity
