Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

What does the gradient in a distance-time graph give you?

A	Numbers
B	Distance value
C	Speed value
D	Acceleration value

Explanation:

Detailed explanation-1: -The gradient of the line of the speed-time graph is the acceleration of the particle (for straight lines acceleration is constant).

Detailed explanation-2: -In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.

Detailed explanation-3: -In a distance-time graph, the slope or gradient of the line is equal to the speed of the object. The steeper the line (and the greater the gradient) the faster the object is moving.

Detailed explanation-4: -The slope of the distance-time graph represents the speed of an object.

Detailed explanation-5: -Thus the slope of a distance time graph at any point gives the velocity of a particle. It is also known as the displacement per unit time. Its unit is ms−1 or metre per second. So, the correct answer is “Option C”.
