Force And Motion – FAQ
Force is a vector quantity that causes an object to change its state of motion or shape. It is measured in newtons (N) and can be described as a push or a pull on an object resulting from its interaction with another object.
Newton’s First Law of Motion states that an object will remain at rest, or in uniform motion in a straight line, unless acted upon by an external force. This law emphasizes the concept of inertia, which is the resistance of an object to any change in its state of motion.
There are several types of forces, including gravitational, electromagnetic, nuclear, and frictional forces. Gravitational force pulls objects toward one another, while electromagnetic force acts between charged particles. Nuclear forces keep atomic nuclei together, and frictional force opposes the motion of objects in contact.
Friction is a force that opposes the relative motion or tendency of such motion of two surfaces in contact. It acts in the opposite direction of motion and can cause objects to slow down or stop. The amount of friction depends on the nature of the surfaces and the force pressing them together.
According to Newton’s Second Law of Motion, the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma). This means that the greater the force applied to an object, the greater its acceleration, provided the mass remains constant.
