The gradient of a velocity-time graph at a particular time gives the acceleration of the object at that time. \(\text{Gradient} = \frac{{change\,in\,velocity ...

How useful is Bernoulli's equation? How restrictive are the assumptions governing ... Lift is defined as the force acting on an airfoil due to its motion, in a direction normal to the direction of ...

Shown below is an animation of the motion of A and B as seen by a stationary observer. The paths of A and B are straight, as expected, with the speed of B increasing in time. View of B as seen by an ...

One of the most fundamental equations in physics, Newton’s Second Law of Motion, was formulated by Sir Isaac Newton in 1687. It states that the force () acting on an object is equal to its mass ...

This equation is called the continuity equation for steady one ... To visualize this in a flow, we could imagine the motion of a small marked element of fluid. For example, we could mark a drop of ...

“By introducing the G-field, we obtain the modified Einstein equations and the equations of motion for the matter and the ...

The motion of objects can be analysed using equations and graphs. These tools allow other aspects of motion such as acceleration and displacement to be determined or modelled. Forces, energy and ...
