KINEMATICS

Question 1

Distance travelled per unit time

S= Distance/Time

Answer 1

Speed

Question 2

Change in position per unit time

• rate at which the object change position

V= displacement/time

Answer 2

Velocity

Question 3

Ś=Total distance/ Total time

Answer 3

Average Speed

Question 4

V= Total displacement/Total time

Answer 4

Average Velocity

Question 5

Value at a specific time in a trip

Answer 5

Instantaneous

Question 6

Rate change of velocity

a= delta velocity/ time

Change in velocity= V final-V initial

Answer 6

Acceleration

Question 7

Acceleration is constant

Vf= Vi + at

d= (Vf + Vi/2)t

d= Vit + ½at²

Vf²= Vi² +2ad

Answer 7

Uniformly Accelerated Rectilinear Motion

Question 8

Object fall wit constant acceleration and disregard air resistance

Answer 8

Free Fall

Question 9

Pressure very low and no external force except gravity=weight of object

Answer 9

Vacuum

Question 10

Combinstion of vertical motion and horizontal motion

Where
Horizontal Motion- constant velocity
Vertical motion-Constant acceleration

Answer 10

Projectile Motion

Question 11

S ⬆️ lost = S ⬇️ gained

t⬆️ = t⬇️

Horizontal component.
ax=0
Vix= Vix cos theta
Delta x= Vix t
tx=ty

Vertical component
ay= g = 9.8 m/s²
Viy= vi sin theta
Delta y = Viy t -½gt²
ty= Viy/g

Answer 11

Projectile Motion without air resistance
