Motion in a Straight Line

Question 1

Area under velocity-time graph

Answer 1

Displacement

Question 2

Slope of velocity-time graph

Answer 2

Acceleration

Question 3

First Equation of Motion

Answer 3

v = u + at

Question 4

Second Equation of Motion

Answer 4

v = ut + ¹/₂at²

Question 5

Third Equation of Motion

Answer 5

v² = u² + 2as

Question 6

Displacement in the nᵗʰ second, sₙ

Answer 6

sₙ = u + ᵃ/₂(2n-1)

Question 7

Point Object

Answer 7

If the size of a body is negligible compared to the distance covered, the body can be considered as a point object.

Question 8

Average acceleration

Answer 8

Average acceleration over a time interval is the change in velocity divided by the time interval.

Question 9

Deceleration

Answer 9

Acceleration in the opposite direction of velocity.
