Motion

Slope of distance time graph represents-

• speed

• acceleration

• displacement

• none of these

SI unit of acceleration is-

• ms^-1

• ms^-2

• ms²

• none of these

Which of the following is a scalar quantity?

• acceleration

• velocity

• distance

• displacement

Rate of change of velocity is called-

• average speed

• average velocity

• acceleration

• none of these

When an object travels equal distance in equal intervals of time, it is said to be in-

• uniform acceleration

• non uniform accelration

• uniform motion

• non uniform motion

Displacement is represented by-

• slope of s-t graph

• slope of v-t graph

• area under s-t graph

• area under v-t graph

Speed of an object is equal to the magnitude of velocity if-

• the object is travelling in uniform circular motion

• the object is travelling along a straight path

• the initial and final positions are same

• none of these

An object moving in a circular path with uniform speed experiences a continuous change in its

• direction

• velocity

• speed

• both a and b

The numerical ratio of distance to displacement is always

• more than 1

• equal to one

• less than or equal to 1

• more than or equal to 1

The nature of s-t graph for rest -

• straight line passing through origin

• straight line parallel to time axis

• straight line perpendicular to time axis

• straight line overlapping time axis
