(Include a free-body diagram as part of your explanation.) ... connected to a ball of mass m2 by a lightweight cord over a lightweight, frictionless pulley as shown in figure. A force of magnitude F at an angle θwith the horizontal is applied to the block as shown and the block slides to the right. The coefficient of kinetic friction between the block and surface is μ k. The horizontal acceleration is zero, and the vertical acceleration is g. We know this because a free-body diagram shows only mg, acting vertically, and applying Newton's second law tells us that mg = ma, so a = g. You can do the same thing with charges in a uniform electric field.

A ball on a string moves in a vertical circle, as shown. When the ball is at its lowest point, is the tension in the string greater than, less than, or equal to the ball's resting weight? Explain fully, using a free-body diagram and accompanying equations. Learn this topic by watching Centripetal Forces Concept Videos. First, draw a free-body diagram and note that F grav = 490 N, down. Second, calculate acceleration by. a = v 2 / R = (16 m/s) 2 / (15 m) = 17.1 m/s/s, up. Then note that F net = m • a = 853 N, up (toward center). Now F grav supplies 490 N of downward force, so the F norm must overcome this down force and still supply the sufficient F net in ... force on the body due to an astronomical body N = mg (5.5) - Normal force: perpendicular force on a body from a surface against which the body presses. - Frictional force: force on a body when the body attempts to slide along a surface. It is parallel to the surface and opposite to the motion.-Tension: pull on a body directed away from the Using free body diagram, show that it is easy to pull an object than to push it. Answer: When a body is pushed at an arbitrary angle θ [0 to $\frac {π}{2}$], the applied force F can be resolved into two components as F sin 0 parallel to the surface and F cos 0 perpendicular to the surface as shown in figure.

So in the case of a pendulum, it is the gravity force which gets resolved since the tension force is already directed perpendicular to the motion. The diagram at the right shows the pendulum bob at a position to the right of its equilibrium position and midway to the point of maximum displacement.

Answer: Cathy is correct. From a free-body diagram for the lower mass, and choosing up as the positive direction, we can apply Newton 's Law to the lower mass. The tension T minus the weight of the lower mass equals the mass m 2 times its acceleration. (on m za = (10kg)(—3 m/s2) = —30 N. So T— g= T — or +98 N -30 N = T ION.
