A quantity described by magnitude and direction both are called

  • scalar
  • vector
  • unit
  • all of above

The motion of a butterfly is an example of

  • vibratory motion
  • circular motion
  • linear motion
  • random motion

A cyclist completes half round of a circle track of radius 420 meters in 3 minutes. Its velocity will be

  • 4.67 ms−1
  • 5.33 ms−1
  • 2.8 ms−1
  • 3.5 ms−1

Distance covered ⁄ time taken is equal to

  • speed
  • velocity
  • displacement
  • position

The total length of the path is named

  • displacement
  • distance
  • length
  • all of above

A passenger John is sitting in a moving car, as per an observer outside the car, he is at

  • position
  • rest
  • motion
  • displacement

(Final velocity - initial velocity) is called

  • position
  • acceleration
  • change in velocity
  • displacement

The velocity of cyclist when he completes half round of a circular track of radius 318 m in 1.5 min is

  • 10 ms-1
  • 8 ms-1
  • 7.07 ms-1
  • 9 ms-1

A bus starts from rest. Its velocity becomes 30 ms−1 in 8s. Its acceleration will be

  • 3 ms−2
  • 5 ms−2
  • 2 ms−2
  • 3.5 ms−2

Gravitational acceleration is denoted by

  • a
  • g
  • r
  • G

The third equation of motion can be represented as

  • Vf = Vi + at
  • 2aS = V2f - V2i
  • 2aS = Vf - Vi
  • none of above

If a body covers equal distances in equal intervals of time however short the interval maybe, then it has

  • uniform velocity
  • uniform speed
  • uniform acceleration
  • non-uniform velocity

A ball is thrown vertically upward. Its velocity at the highest point is

  • zero
  • 10 ms−1
  • 15 ms−1
  • 20 ms−1

A straight line parallel to time-axis on a distance-time graph tells that the object is

  • at rest
  • in motion
  • moving with constant speed
  • moving with variable speed

The quantities between which graph is plotted is called

  • scalars
  • vectors
  • variables
  • base

The velocity of ball at highest point when its thrown vertically upward is

  • -10 ms-1
  • 10 ms-2
  • 8 ms-1
  • zero

A car start from rest. It moves through 2 km in 100 s with uniform acceleration. Its speed at the end of 100 s will be

  • 80 −1
  • 20 −1
  • 40 ms−1
  • 10 −1

The rate of change of velocity of a body is called its

  • displacement
  • acceleration
  • speed
  • distance

A passenger John is sitting in a moving car, so with respect to other passengers he is at

  • rest
  • motion
  • displacement
  • position

The value of gravitational acceleration is approximately

  • 15 ms−2
  • 25 ms−2
  • 10 ms−2
  • 5 ms−2
