# Uniformly accelerated motion

Hence, the velocity of the second object becomes 1. See Article History Alternative Title: Motion along a line or a curve is called translation. Motion that changes the orientation of a body is called rotation.

## Practice questions on motion

In both cases all points in the body have the same velocity directed speed and the same acceleration time rate of change of velocity. The most general kind of motion combines both translation and rotation. All motions are relative to some frame of reference. Saying that a body is at rest, which means that it is not in motion, merely means that it is being described with respect to a frame of reference that is moving together with the body.

For example, a body on the surface of the Earth may appear to be at rest, but that is only because the observer is also on the surface of the Earth. The Earth itself, together with both the body and the observer, is moving in its orbit around the Sun and rotating on its own axis at all times.

However, motion at speeds close to the speed of light must be treated by using the theory of relativityand the motion of very small bodies such as electrons must be treated by using quantum mechanics.

Uniformly accelerated motion starting at zero velocity gives rise to a triangular figure (see the figure).It was proved by the Merton school that the quantity of motion in such a case is equal to the quantity of a uniform motion at the speed achieved halfway through. Thus, uniform accelerated motion means motion with constant acceleration. Change in Notation To emphasize the notion that this motion is not a general motion, the following simplifications and change in notation are considered.

Uniform Acceleration Motion: Problems with Solutions Problems on velocity and uniform acceleration are presented along with detailed solutions and tutorials can also be found in this website.

Problem 1: From rest, a car accelerated at 8 m/s 2 for 10 seconds. Mechanics: Mechanics, science concerned with the motion of bodies under the action of forces, including the special case in which a body remains at rest. Of first concern in the problem of motion are the forces that bodies exert on one another.

This leads to the study of such topics as gravitation.
