WebAug 11, 2024 · Figure 2.5. 1: (a) Velocity-versus-time graph with constant acceleration showing the initial and final velocities v 0 and v. The average velocity is 1 2 (v 0 + v) = 60 km/h. (b) Velocity-versus-time graph with an acceleration that changes with time. The average velocity is not given by 1 2 (v 0 + v), but is greater than 60 km/h. WebAcceleration. As mentioned earlier in Lesson 1, an object moving in uniform circular motion is moving in a circle with a uniform or constant speed. The velocity vector is constant in magnitude but changing in direction. Because the speed is constant for such a motion, many students have the misconception that there is no acceleration.

WebOct 6, 2024 · And since the particle is moving in uniform uniformity, the change in velocity will be zero. Then the acceleration of the particle will be zero.

For an object with constant velocity, the position can be calculated as WebIf the acceleration of a body is not zero, then its velocity can be constant. Q. can a body have constant acceleration but zero velocity. Q. Can the velocity be 0 but acceleration be non zero? Q. Assertion :If the net force on a rigid body is zero, it is either at rest or moving with a constant linear velocity. Nothing else can happen.

WebWe can find acceleration using either a mathematical technique or a graphical method, depending on whether the velocity is constant or not. Because it is the ratio of change in velocity to change in time, while velocity is constant, the change in velocity is zero, so the acceleration is zero.
