Answer 2

Slope of a distance-time graph represents a physical quantity which has the unit d) m/s.

The object is a) in uniform motion.

Explanation:

• In a distance-time graph, y-axis represents distance and x-axis represents time.

• The slope of graph is given as:

$slope=\frac{y-axis}{x-axis}$$slope=\frac{y-axis}{x-axis} =\frac{distance}{time}$

• Rate of distance covered per unit time is called speed.
• Slope of distance-time graph gives speed.

• Speed informs how fast or slow the body is moving. SI unit for speed is $m/s$.

• In the fig, the change in displacement is linear with respect to time.

• The slope of displacement-time graph shows gradual constant motion as the slope is a straight line.

• At any point on the line, the slope is same, so the body is said to be in uniform motion i.e. same speed throughout its motion.
