... frictionless the force it exerts is normal to the plank and makes the angle with the vertical. Its magnitude is designated F. W is the force of gravity; this force acts at the center of the plank, a distance L/2 from the point where the plank touches the floor. FN is the normal force of the floor ...

... depending on the direction the force tends to rotate an object. • We will use the convention that the sign of the torque is positive if the rotation is counterclockwise and negative if the rotation is clockwise. Tip: To determine the sign of a torque, imagine that the torque is the only one acting o ...

... Questions to Answer: a) If the person’s speed at the instant shown was the same 0.3 m/sec but it was increasing instead of remaining constant, would the magnitude of the vector representing the net force acting on the person at that instant be less than, equal to or greater than it was before? Would ...

... The amount by which the forces acting on an object are unbalanced is called the net force. When the forces acting on an object are unbalanced, the object will accelerate. Because acceleration is a change in velocity, and velocity includes both speed and direction, a net force will change the speed a ...
