Equations of Motion starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Equations of 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
Derive the second equation of motion using calculus.
Explain why the equations of motion are not valid for variable acceleration.
If an object moves with constant velocity, what is its acceleration?
State the three standard equations of motion for uniformly accelerated linear motion.
The first equation of motion is v = u + at. What does each symbol represent?
A ball is thrown downward with a velocity of 5 m/s from a height of 45 m. How long will it take to reach the ground? (g = 10 m/s2)
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 moves with an initial velocity of 10 m/s and an acceleration of 2 m/s2. What is its velocity after 6 seconds?

(2) Decrease
(3) Remain constant
(4) Become zero
