In case of a moving body
WebIn the case of the streamlined body the wake zone is too small. Fluid pressure does not contribute to drag. Shear stresses along the contact surfaces are parallel to the direction of fluid motion and hence the drag is practically a shear drag. General Equation for the Force Exerted on a Body Placed in a Moving Fluid: WebSep 27, 2024 · That situation is described by Newton's Second Law of Motion. According to NASA, this law states, "Force is equal to the change in momentum per change in time. For a constant mass, force equals ...

Did you know?
WebCorrect option is D) According to law of inertia or Newton's first law of motion, a body in state of rest or of uniform motion remains in state of rest or of uniform motion unless it is acted upon by an external force. Hence a body in uniform motion required no force to keep them in uniform motion. Given that force = mass x acceleration WebApr 6, 2024 · Therefore, the distance-time graph of the body moving with uniform speed is straight line passing through the centre as shown in the figure below, (iii) When the body is moving in non- non-uniform speed and uniform acceleration: As we know, \[a = \dfrac{{dv}}{{dt}} = \dfrac{{{d^2}x}}{{d{t^2}}}\]. Therefore, the distance-time graph will be …
WebMay 29, 2024 · Explanation: The correct answer is 1. A moving body is traveling both distance and displacement. As it is moving it is travelling both distance and displacement. … WebNewton’s first law of motion states the following: A body at rest tends to remain at rest. A body in motion tends to remain in motion at a constant velocity unless acted on by a net external force. (Recall that constant velocity means that the body moves in a straight line and at a constant speed.) At first glance, this law may seem to ...
WebMar 16, 2024 · When a body moves along a straight-line path, its motion is called the one-dimensional motion or motion in a straight line or rectilinear motion.
