# Mcqs On Motion

Q:

### If the displacement of an object is proportional to square of time, then the object moves with

 Increasing acceleration Uniform acceleration Uniform velocity Decreasing acceleration
Q:

### The numerical ratio of displacement to distance for a moving object is

 always more than 1 more than or equal to 1 always less than 1 less than or equal to 1
Q:

### The total path length travelled by a body in a given interval of time is called

 Displcement Uniform motion Acceleration Distance
Q:

### A car is travelling at a speed of 90 km/h. Brakes are applied so as to produce a uniform acceleration of – 0.5 m/s2. Find how far the car will go before it is brought to rest?

 980 m 625 m 1620 m 620 m
Q:

### Suppose a boy is enjoying a ride on a marry go round which is moving with a constant speed of 10 ms-1. It implies that the boy is

 In accelerated motion At rest Moving with no acceleration Moving with uniform velocity
Q:

### A car of mass 1000 kg is moving with a velocity of 10 m/s. If the velocity-time graph for this car is a horizontal line parallel to the time axis, then the velocity of the car at the end of 25 s will be

 25 m/s 10 m/s 10.5 m/s 90 m/s
Q:

### A particle is moving in a circular path of radius r. The displacement after half a circle would be

 Zero π r 2 r 2π r
