4. Measurement and Effects of Force

Force is a vector quantity that causes an object to change its state of motion or shape, measured in Newtons (N). Various types of force, including contact and non-contact forces, influence motion, leading to effects such as changes in velocity, shape, and rotation. Understanding Newton's laws, the measurement of force through instruments, and the role of friction is essential for grasping the applications and implications of force in mechanical systems.
