Detailed Solution

Slope of the Distance-Time graph gives velocity.
The slope of the Distance-Time graph will be Distance/time, which is nothing but the velocity.
Question ImageSlope = Distance / time
 We know that
velocity = Distance/time
So the slope of the Distance-Time graph is equal to velocity.
Velocity can be defined as the "rate of change of position of an object to time", and the SI unit for velocity is m/s. Velocity has magnitude and direction; hence it is a vector quantity.
Acceleration is the rate of change of an object's velocity to time. Acceleration is a vector quantity (as it has magnitude and direction). SI unit of acceleration is m/s2.. Retardation or deceleration occurs when velocity decreases over time. Negative acceleration is commonly known as retardation. It has the SI unit as m/s2. The product of mass and velocity is known as the momentum.
