Kinematics Graphs MCQ - Practice Questions with Answers

I.  Position time graph-

Motion of an object can be represented by a position time graph.

Such a graph is very useful for analyzing different aspects of motion of an object.

Slope of the position-time graph represents the velocity of the particle

1. Position time graph when the body is at rest 

     

 

Figure shows position time graph when the body is at rest 

Position time graph for a stationary object is a straight line.

 

2. Position time graph for uniform motion

      

Figure shows position-time graph for uniform motion.

Here object is moving along a straight line and covers equal distances in equal intervals of time.

 

3.  Position – time graph For objects in non-uniform motion

The figure shows position-time graph for non-uniform motion.

Here the object is moving along a straight Line and covers an equal distance in unequal time intervals.

 II.   Velocity Time Graph

The graph is plotted by taking time t along the x-axis and the velocity of the particle on the y-axis.

• The area of the velocity v/s time graph for the particular time interval gives the displacement and distance traveled by the body for a given time interval.

• The slope of the velocity-time graph represents the acceleration of the particle.

1. When a particle is moving with constant velocity.

2. For  uniform acceleration of the particle

3. Particles having constant Negative Acceleration

4. A particle having constant Positive Acceleration

5. Particles having  increasing acceleration 

6. Particles having  decreasing acceleration

7. A particle having Zero Acceleration

The velocity Vs time graph for Zero Acceleration will be a line parallel to the time axis.

 

III.  Acceleration-Time graph  

The graph is plotted by taking time t along the x-axis and the acceleration of the particle on the y-axis.

• The area of the acceleration v/s time graph for the particular time interval gives the change in velocity of the body for a given time interval.

• The slope of the acceleration-time graph represents the jerk.

1. When a particle has Constant acceleration

2. Particle having uniformly increasing acceleration

3. A particle having non-uniformly increasing acceleration
