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 11
A ball is thrown vertically upwards with a velocity of 20 m/s. What is the maximum height it reaches? (Take g = 10 m/s²)
A bus starts from rest and attains a speed of 25 m/s in 10 seconds. What is its acceleration?
A car accelerates from rest at 4 m/s². How far does it travel in 3 seconds?
A car moves with a velocity of 20 m/s for 10 seconds and then with 30 m/s for another 10 seconds. What is its average velocity?
A car travels 100 m north and then 100 m east. What is the magnitude of its displacement?
A cyclist covers a distance of 1200 m in 4 minutes. What is his average speed in m/s?
A runner completes one lap of a 400 m circular track in 80 seconds. What is his average velocity?
A stone is dropped from a height of 45 m. How long does it take to reach the ground? (Take g = 10 m/s²)
A train moves with a constant speed of 60 km/h for 30 minutes. How far does it travel?
Define average velocity.
Explain why the distance traveled is always greater than or equal to the magnitude of displacement.
If a body starts from rest and accelerates uniformly at 2 m/s² for 5 seconds, what is its final velocity?
If an object moves in a straight line and returns to its starting point, what is its displacement?
If the velocity of an object changes from 10 m/s to 30 m/s in 4 seconds, what is its acceleration?
If the velocity-time graph of an object is a straight line parallel to the time axis, what can you say about its motion?
State the difference between instantaneous speed and average speed.
Write the three equations of motion for uniformly accelerated linear motion.
