Equations of Motion
Physics ⇒ Mechanics
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 11

If a car starts from rest and accelerates uniformly at 3 m/s2 for 4 seconds, what is its final velocity?
If the acceleration of an object is zero, what can you say about its velocity?
If the initial velocity is 0, which equation of motion simplifies to s = 1/2 at2?
State the three equations of motion for an object moving with uniform acceleration.
The initial velocity of a body is 10 m/s. It moves with a uniform acceleration of 2 m/s2. What is its velocity after 6 seconds?
A body moves in a straight line with an initial velocity of 12 m/s and a constant acceleration. If it covers 180 m in 6 seconds, what is its acceleration?
A car is moving with a velocity of 30 m/s. The driver applies brakes, producing a uniform acceleration of -5 m/s2. How far will the car travel before coming to rest?
