Question

The displacement-time graph of a moving object is a straight line. Then,​

Answer 1

Answer:

then , we can say that th displacement is decrasing ot increasing uniformly, means that the rate of change of displacement (velocity) is contant /uniform

Explanation:

Answer 2

When a displacement -time graph is a straight line, two things can happen, either it is a positive slope straight line or it is a horizontal line.

Explanation:

Case 1: Horizontal line

• A slope in displacement-time graph gives velocity.
• A horizontal line in displacement-time graph is a line with zero slope.
• Here, the displacement is constant as time passes. There is no change in displacement with time.
• Body is stationary i.e. at rest because the velocity is zero.

Case 2: Increasing slope line

• A slope in displacement-time graph gives velocity.
• A linear inclined line in displacement-time graph is a line with positive slope.
• Here, the displacement is increasing uniformly with time.
• Body is moving with uniform velocity as the slope is a straight line and is positive.
