When the slope of vt graph is VE and constant What is the nature of acceleration plot graph also?

Slope of velocity time graph gives acceleration. If body moves with constant velocity then acceleration will be zero. So slope of v-t graph will be zero.

When the slope of velocity time graph is negative and constant What is the nature of acceleration?

The Importance of Slope If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line). If the acceleration is negative, then the slope is negative (i.e., a downward sloping line).

What does a negative slope mean on a velocity time graph?

Negative velocity and positive slope,: object is slowing down. Velocity-Time Graphs. If the V-T line has a negative slope, the object is undergoing acceleration in the negative direction.

How can you tell if acceleration is constant from a velocity time graph?

If the line slopes upward, like the line between 0 and 4 seconds in the Figure above, velocity is increasing, so acceleration is positive. If the line is horizontal, as it is between 4 and 7 seconds, velocity is constant and acceleration is zero.

What does it mean if the acceleration is 0?

If acceleration is 0, the velocity is not changing. If the velocity is constant (0 acceleration) then the object will continue without slowing down or speeding up.

What do you mean by zero positive and negative acceleration?

【 In vector form , if angle between velocity vector and acceleration vector is less than 90° and greater than 0° then it is positive acceleration and if it is less than 180° and greater than 90° then it is negative acceleration. If there is no acceleration vector then it is called zero acceleration. 】

What is the body’s acceleration each time the velocity is zero?

Find the body’s speed each time the acceleration is zero. Since a(t)=6t-12 = 0 when t = 2 and the speed function is sp(t) = |v(t)|, the answer is |v(2)| = 3m/sec.

How do you find acceleration when velocity is zero?

Check Your Understanding

  1. The velocity function is the integral of the acceleration function plus a constant of integration. By (Figure), Since v(0) = 0, we have C1 = 0; so,
  2. By (Figure), .Since x(0) = 0, we have C2 = 0, and.
  3. The velocity can be written as v(t) = 5t(1 – t), which equals zero at t = 0, and t = 1 s.
