A 0.25-kg ball attached to a string is rotating in a horizontal circle of radius 0.5 m. If the ball revolves twice every second, what is the tension in the string?
The formula for calculating tension in a string is T = (m*v^2)/r, where T is tension, m is the mass of the object, v is the velocity of the object, and r is the radius of the circular motion.
In this scenario, the mass of the object is given as 0.25 kg.
The value of 2 Hz represents the frequency at which the ball is revolving, which is the number of revolutions per second. It is an important factor in calculating tension in a string as it affects the velocity of the object in the formula.
The radius of the circular motion is directly proportional to tension in the string. This means that as the radius increases, the tension in the string also increases.
No, there may be other forces acting on the object such as gravity or friction. However, the formula for tension in a string only takes into account the centripetal force required to keep the object in circular motion.
