#### Question 1. For the motion with uniform velocity, how is the distance travelled related to the time?

Answer : Distance is directly proportional to time.

Question 2. What does the slope of a displacement-time graph represent?

Answer : Slope of a displacement-time graph represents velocity.

Question 3. When can the distance time and displacement time graph be the same ?

Answer : For motion in one direction since the direction of motion does not change, so displacement-time graph and the distance-time graph are same.

Question 4. What informations do we get by a greater slope of displacement time graph ?

Answer : Displacement-time graphs – Higher

A sloping line on a displacement-time graph shows that the object is moving.

Question 5. What information is conveyed about motions by the negative slope of a displacement time graph ?

Answer : The slope of a displacement-time graph gives the velocity. If the slope is positive, it indicates that the body is moving away from the reference or the starting point. If the slope is negative, the body is reverting to the initial point.

#### Question 6. What does the slope of velocity-time graph represent?

Answer : The slope of the velocity-time graph represents acceleration.

#### Question 7. What information do we get by a higher slope of velocity-time graph ?

Answer : If the slope of graph is positive then it will acceleration, and if slope is negative then it will be retardation.

Question 8. What information do we get about motion by the negative slope of a velocity-time graph ?

Answer : Therefore, the slope of the velocity-time graph represents the acceleration of the object. Hence, if the slope is negative, this means the velocity of the object is decreasing with time.
