6 days ago · The equations of motion of kinematics describe the most fundamental concepts of motion of an object. These equations govern the motion of an object in 1D, 2D and 3D. They can easily be used to calculate expressions such as the position, velocity, or acceleration of an object at various times.
2 days ago · Work and energy. The work W done by a constant force of magnitude F on a point that moves a displacement s in a straight line in the direction of the force is the product. For example, if a force of 10 newtons ( F = 10 N) acts along a point that travels 2 metres ( s = 2 m ), then W = Fs = (10 N) (2 m) = 20 J.

4 days ago · ACCELERATION. Acceleration is the measurement of how quickly the velocity of an object is changing, usually with respect to time. If you measure the velocity of an object at a particular time (Time 1), then again at a subsequent time (Time 2), then the average acceleration which the object has experienced will be:
4 days ago · Velocity and acceleration are vectors quantities; they have both magnitude as well as direction. By Newton’s second law, acceleration acts on a body if external forces are acting on it. If there are no external forces acting on a body, the body moves with uniform velocity or remains at rest.
