gravity and moons forces pulls it up
At the highest point of its swing, the string tension and the force of gravity acting downwards will be the only forces on the rock. The tension force will point downward and the gravitational force will point towards the center of the circle.
When the lever is level and unmoving, the forces acting on the rock are gravity pulling it downward and the normal force pushing it upward to support its weight. Additionally, there may be friction forces acting between the rock and the lever to keep it in place.
When the rock starts to roll, it suggests that the combined force from the people pushing is greater than the forces resisting the rock's movement, such as friction. This demonstrates that the net force acting on the rock is in the direction of motion.
When a rock is sitting on the ground, there are two main forces acting on it: the gravitational force pulling the rock down towards the center of the Earth, and the normal force exerted by the ground pushing back up against the rock to prevent it from sinking into the Earth's surface. These two forces are equal in magnitude and opposite in direction, resulting in the rock remaining at rest.
Gravity and air resistance.
Rock tension is the stress in a rock mass caused by stretching or pulling forces acting on the material. This can lead to fractures, faulting, and other forms of rock deformation. Understanding rock tension is important in geology and engineering to assess the stability of rock structures and prevent failures.
At the highest point of its swing, the string tension and the force of gravity acting downwards will be the only forces on the rock. The tension force will point downward and the gravitational force will point towards the center of the circle.
The force that changes a rock's shape or volume is called stress. This can occur due to factors such as compression, tension, or shear forces acting on the rock.
Normal Fault
a result of compression forces acting on plates is massive folding and faulting of rock
When the lever is level and unmoving, the forces acting on the rock are gravity pulling it downward and the normal force pushing it upward to support its weight. Additionally, there may be friction forces acting between the rock and the lever to keep it in place.
that they are greater than the forces keeping the rock from moving...
dont be lazy and keep looking
If the rock is in a river it gets smoothed. Those would be the forces of gravity and self weight as well as in-situ stresses which may cause compression, tension or shear.
Features that involve tension include fault lines, mountain ranges, cliffs, and folds in rock layers. Tension forces can cause these features to form as the Earth's crust responds to the stress.
gravity its always acting on you
When the rock starts to roll, it suggests that the combined force from the people pushing is greater than the forces resisting the rock's movement, such as friction. This demonstrates that the net force acting on the rock is in the direction of motion.
