Addition Of Forces Since force is a vector quantity, forces can be represented by an arrow diagram. Resultant Force Resultant force is the combination of 2 or more forces. Adding Forces In Same Direction The above figure shows two forces – 10 N and 20 N acting on a car. The resultant force will be 30 N to the right, …
Momentum (Or Linear Momentum) Linear momentum is a foundational concept in physics, encapsulating an object’s motion and its intrinsic characteristics. Linear momentum of an object is a measure of its motion, combining both its mass and its velocity. It is a vector quantity, denoted by $\vec{p}$, and is defined as the product of an object’s mass $m$ and its velocity …

Friction Friction is the force that resists the motion of one surface relative to another with which it is in contact. It is parallel to the contact surfaces and opposite to the direction of motion or impeding motion. Body In Motion Friction between a moving object and its environment plays a crucial role by acting to diminish the object’s velocity. …
