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 8
Explain the meaning of each symbol in the equation s = ut + 0.5at2.
Explain why the equations of motion cannot be used for objects moving with variable acceleration.
If an object moves with a constant velocity, what is its acceleration?
State the three equations of motion for uniformly accelerated motion.
A ball is dropped from a height of 45 meters. How long will it take to reach the ground? (Take g = 10 m/s2)
A ball is thrown upwards with an initial velocity of 20 m/s. If acceleration due to gravity is -10 m/s2, how long will it take to reach the highest point?
A ball is thrown vertically upwards with a velocity of 15 m/s. How high will it rise? (Take g = 10 m/s2)
