It is true.
Pressure causes mechanical weathering by exerting force on rocks, leading to stress and cracks in the rock structure. Over time, the pressure causes the rocks to break down into smaller pieces. This process is known as stress release weathering.
Gravity plays a key role in weathering by influencing the movement of rocks and sediments downhill. The force of gravity causes rock fragments to be transported, eroded, and deposited in different locations, contributing to mechanical and chemical weathering processes. Overall, gravity helps to shape the Earth's surface and drive the cycle of weathering and erosion.
When an applied force causes rock to break, it typically results in the formation of cracks or fractures in the rock. These cracks propagate through the rock as the force is applied, eventually leading to the rock breaking into smaller pieces or fragments. The extent of the breakage will depend on factors such as the type of rock, its structure, and the magnitude of the applied force.
Weathering is generally considered a destructive force because it breaks down rocks and minerals into smaller particles through processes like physical weathering (e.g. frost action) or chemical weathering (e.g. oxidation). However, it can also contribute to soil formation and the creation of new landforms when combined with other processes like erosion and deposition.
The process of tree roots cracking concrete foundations is primarily considered a mechanical weathering process. In this case, the physical force exerted by the growing roots causes the concrete to crack. Chemical weathering involves changes in the chemical composition of materials, which is not the primary factor in this scenario.

Kinetics
The force that causes galaxies to move away from one another in the universe is called dark energy.
False. A pulley system can change the direction of the force applied, but it does not always result in the output force being in the opposite direction of the input force. The direction of the output force depends on the configuration of the pulleys in the system.
it is the force
The force that causes a change in the motion of an object is called an external force. This force can come from various sources, such as gravity, friction, or contact with another object.
The statement is not true. But to simply call it "false" hardly does it justice. It's monumentally, archetypically, stunningly false, from at least three angles if not more. -- Energy is not a force at all. -- No force is necessary to cause an object's displacement from one place to another. -- A moving object has energy, and a stationary object may also have energy, but no energy is necessary to cause an object's displacement from one place to another, and none of the energy it has needs to be used up in order to accomplish its displacement.
Force of Gravity.
Gravity plays a key role in weathering by influencing the movement of rocks and sediments downhill. The force of gravity causes rock fragments to be transported, eroded, and deposited in different locations, contributing to mechanical and chemical weathering processes. Overall, gravity helps to shape the Earth's surface and drive the cycle of weathering and erosion.
Gravitational pull
True. When a ball is thrown into the air, Earth's gravitational force causes the ball to accelerate downward, creating an unbalanced force.
