When a car moves with constant velocity, its acceleration is: Variable Increasing Zero Decreasing 3 / 15 3. The area under a velocity-time graph represents: Distance Acceleration Force Speed 4 / 15 4. A freely falling body has: Decreasing acceleration Uniform velocity Uniform acceleration Zero acceleration 5 / 15 5. A body is said to be at rest if: It changes position with time It moves with uniform velocity It does not change position with time It moves with uniform acceleration 6 / 15 6. Which of the following is a vector quantity? Speed Distance Length Velocity 7 / 15 7. Acceleration is defined as: Rate of change of time Rate of change of distance Rate of change of velocity Rate of change of speed 8 / 15 8. If a car starts from rest and accelerates uniformly at 2 m/s² for 5 seconds, what is its velocity? 20 m/s 10 m/s 5 m/s 2 m/s 9 / 15 9. What is the SI unit of velocity? m m/s km/h cm/s 10 / 15 10. If the velocity of an object changes by equal amounts in equal intervals of time, the acceleration is: Increasing Constant Decreasing Zero 11 / 15 11. A body moves with a constant speed in a circle. Which of the following is true? Its velocity is constant Its speed is constant Its direction is constant Its acceleration is zero 12 / 15 12. The initial velocity (u) of a body is 0, it attains a velocity (v) in time t with acceleration a. Which formula is correct? v = u × at v = u + at v = u - at v = u / at 13 / 15 13. The slope of a distance-time graph gives: Force Velocity Displacement Acceleration 14 / 15 14. Which formula is correct for acceleration (a)? a = v/t a = t/v a = u/t a = (v - u)/t 15 / 15 15.
