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
A body moves with a constant velocity. What is its acceleration?
Describe the physical meaning of each term in the equation s = ut + 1/2 at2.
Explain why the equations of motion cannot be used for motion with variable acceleration.
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?
A ball is thrown downward with a velocity of 5 m/s from a height of 20 m. How long will it take to reach the ground? (Take g = 10 m/s2)
A ball is thrown vertically upward with an initial velocity of 20 m/s. How long will it take to reach its maximum height? (Take g = 10 m/s2)
A body starts from rest and travels 80 m in 4 seconds with uniform acceleration. What is its acceleration?
A car accelerates from 0 to 20 m/s in 10 seconds. What is the average velocity during this time?
Which equation of motion is independent of time? (1) v = u + at (2) s = ut + 1/2 at2 (3) v2 = u2 + 2as (4) s = vt
Which equation of motion would you use to find the final velocity if you know the initial velocity, acceleration, and displacement? (1) v = u + at (2) s = ut + 1/2 at2 (3) v2 = u2 + 2as (4) s = vt
Which of the following is a correct expression for displacement when initial velocity, acceleration, and time are known? (1) s = ut + 1/2 at2 (2) s = vt + 1/2 at2 (3) s = u + at (4) s = v2 - u2 / 2a
Which of the following is NOT a requirement for using the equations of motion? (1) Constant acceleration (2) Straight-line motion (3) Variable acceleration (4) Known initial conditions
