Kinematics of Linear Motion starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Kinematics of Linear Motion.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

Define instantaneous velocity.
Explain the difference between average speed and instantaneous speed.
If an object moves in a straight line and returns to its starting point, what is its net displacement?
If an object moves with a constant speed in a straight line, what can you say about its acceleration?
State the SI unit of acceleration.
A ball is thrown vertically upward with a velocity of 20 m/s. How long will it take to reach the highest point? (Take g = 10 m/s²)
A body starts from rest and travels 100 m in 5 seconds with uniform acceleration. What is the value of the acceleration?
A car accelerates from 15 m/s to 25 m/s in 5 seconds. What is its acceleration?
A car moving at 25 m/s comes to rest in 10 seconds. What is its acceleration?
If the acceleration of an object is zero, which of the following is true?
(1) The object is at rest
(2) The object moves with constant velocity
(3) The object moves with increasing speed
(4) The object moves with decreasing speed
If the velocity of an object is negative and its acceleration is positive, what happens to the object's speed?
(1) Increases
(2) Decreases
(3) Remains the same
(4) Becomes zero
Which of the following graphs represents uniform acceleration?
(1) A straight line in a velocity-time graph
(2) A curve in a displacement-time graph

(4) Path length
The area under a velocity-time graph represents ________.
The rate of change of velocity is called ________.
The slope of a displacement-time graph gives ________.
Can the average velocity of an object be zero even if its average speed is not zero? (Yes/No)
Is it possible for an object to have zero velocity and non-zero acceleration at the same instant? (Yes/No)
True or False: Acceleration can be negative.
True or False: The magnitude of displacement is always equal to the distance traveled.
