AboutPressCopyrightContact... WebSuppose a block moves across a rough horizontal surface at constant speed under the action of a horizontal 3-N force. Which statement concerning this situation is false? a. The block is not accelerated b. The net force on the block is zero newtons c. The frictional force on the block has a magnitude of 3-N. d.
WebApr 21, 2024 · We're going to assume that the block is on earth, we're assuming that it's stationary. Well, if it's on earth, the block has some weight. You have the force of gravity acting on the block. And so let me draw that in my free body diagram. So you're gonna have a … Weba. a dynamic influence that changes a body from a state of rest to one of motion or changes its rate of motion. The magnitude of the force is equal to the product of the mass of the …
WebIf given a description of a physical situation, begin by using your understanding of the force types to identify which forces are present. Then determine the direction in which each force is acting. Finally, draw a box and add arrows for each existing force in the appropriate direction; label each force arrow according to its type. WebConstant motion refers to any type of motion when either the distance traveled by the object is the same for each second, or the speed of the object changes by the same amount …

When a greater normal force is exerted, the actual … somebody\u0027s mother poem summaryWebSince Newton's first law states that when the net force is zero, the object maintains a constant velocity. And for the net force to be zero, these forces have to cancel. So, even though it's non-intuitive, this cable force has to equal the force of gravity, so that the elevator can move with constant velocity. small business laser printer all in oneWebThere are different types of friction—kinetic and static.
