SSC MTS EXAM

Detailed explanation-1: -The slope of a speed-time graph indicates the rate of change of speed of the body and it is the acceleration.

Detailed explanation-2: -A sloping line on a speed-time graph represents an acceleration . The sloping line shows that the speed of the object is changing. The object is either speeding up or slowing down. The steeper the slope of the line the greater the acceleration.

Detailed explanation-3: -(b) The acceleration is defined as the rate of change of speed. So, the slope of the Speed (a velocity) arid Time graph gives acceleration.

Detailed explanation-4: -The gradient of the line of the speed-time graph is the acceleration of the particle (for straight lines acceleration is constant). Gradient of line=change of velocitytime, =v−ut, =a.
