When an object is pulled towards another object or in a specific direction, a pulling force is exerted. This force can be applied through various means such as a rope, string, or any other pulling mechanism.
The magnitude of the pulling force can be influenced by various factors, such as:
Surface type: The nature of the surface in contact with the object being pulled can affect the amount of friction and hence the pulling force required.
Weight of the object: Heavier objects require a greater pulling force to move them.
Angle of pull: The angle at which the force is applied can affect the overall pulling force needed.
The student demonstrates an understanding of how science explains changes in life forms over time, including genetics, heredity, the process of natural selection and biological evolution by showing the relationship between physical characteristics of Alaskan organisms and the environment in which they live.
