Mar 12, 2024 · Understand Newton’s second law of motion. Apply Newton’s second law to determine the weight of an object. Newton’s second law of motion is closely related to Newton’s first law of motion. It mathematically states the cause and effect relationship between force and changes in motion.
Newton's laws are often stated in terms of point or particle masses, that is, bodies whose volume is negligible. This is a reasonable approximation for real bodies when the motion of internal parts can be neglected, and when the separation between bodies is much larger than the size of each.

In areas of more resistant cliff material erosion is greatest when waves break at the foot of a cliff. This causes erosion at the base of the cliff. This creates a wave-cut notch in the base of the cliff. As the notch increases in size, the weight of the cliffs above becomes too much to support, leading to a landslide. This material will provide te...
A rockfall involves rock fragments breaking away from the cliff face, often due to freeze-thawweathering. The video below shows a series of rock falls above a landslide at Port Mulgrave, Yorkshire.
Mudslides occur when saturated soil and weak rock flow down a slope. These typically occur where cliffs are made up of boulder clay. The image below shows a mudslide at Mappleton, Holderness Coast. The video below shows evidence of a mudslide at Mappleton. The video below shows evidence of a small mudflow at Hornsea, Holderness Coast. You can view ...
Identify and describe types of mass movement. In this section, you will learn the term mass wasting. You will also be exposed to the various types of mass wasting, their causes and their effects.
The answer is equally simple: “If a body is accelerating, then there is a force on it.” That is what Newton’s laws say, so the most precise and beautiful definition of force imaginable might simply be to say that force is the mass of an object times the acceleration.
Although many types of mass movements are included in the general term “landslide,” the more restrictive use of the term refers only to mass movements, where there is a distinct zone of weakness that separates the slide material from more stable underlying material.
Sep 14, 2024 · Newton’s laws of motion - Force, Mass, Acceleration: Newton’s second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. The momentum of a body is equal to the ...
