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.
See sample questions for grade 12
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?
A car starts from rest and accelerates uniformly at 2 m/s² for 5 seconds. What is its final velocity?
A car travels at 60 km/h for 30 minutes and then at 90 km/h for 30 minutes. What is the average speed for the whole journey?
A cyclist covers the first half of a distance at 10 km/h and the second half at 20 km/h. What is the average speed for the entire journey?
A particle moves along a straight line with an initial velocity of 5 m/s and a constant acceleration of 3 m/s². What is its displacement after 4 seconds?
A runner completes a 400 m lap in 50 seconds. What is the magnitude of his average velocity?
A stone is dropped from a height of 80 m. How long does it take to reach the ground? (Take g = 10 m/s²)
A train travels 120 km in 2 hours and then 60 km in 1 hour. What is its average speed for the entire journey?
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.
State the three equations of motion for constant acceleration.
The velocity of an object at time t is given by v(t) = 3t + 2. What is the acceleration of the object?
Write the equation of motion relating displacement (s), initial velocity (u), time (t), and acceleration (a).
