Tension from string upon a rock is the force exerted by a string on a rock when the string is pulled tight. This force is directed away from the rock and is caused by the tension in the string.
Tension from string upon a rock can be calculated using the formula T = F * sin(θ), where T is the tension, F is the force applied to the string, and θ is the angle between the string and the rock.
The tension from string upon a rock is affected by the magnitude of the force applied to the string, the angle between the string and the rock, and the properties of the string such as its length, thickness, and elasticity.
The tension from string upon a rock can cause the rock to accelerate in the direction of the tension if the force is greater than the weight of the rock. It can also keep the rock in place if the tension is equal to the weight of the rock.
Yes, tension from string upon a rock can be used to lift the rock if the force applied to the string is greater than the weight of the rock. This can be seen in situations such as rock climbing, where climbers use ropes to lift themselves up.
