Mass measures the amount of matter an object contains and it is a fundamental property of an object. It remains constant irrespective of the object's location, it is a scalar quantity. The SI unit of mass is the kilogram (kg). On the other hand, weight is a vector quantity and refers to the force exerted on an object due to gravity. The SI unit of weight is the Newton (N).Mathematically, the relation between mass and weight is given by W=mg, W=weight, m= mass, and g=acceleration due to gravity. The g's value varies based on the location. Therefore, while the mass of an object remains constant, the weight can change depending on the gra

Momentum has both magnitude and direction and it is a vector quantity. The direction of the momentum is the same as the direction of the velocity. It quantifies the "quantity of motion" of an object and reflects how fast it is moving and how much mass the object has, the standard SI unit for momentum is kilogram-meters per second (kg m/s). A heavier object moving a the same velocity as the lighter object will have greater momentum. Also, an object moving at a higher velocity will have higher momentum than the same object moving at a lower velocity.

When all the forces act on a single object, a free body diagram (FBD) graphically represents these forces. It helps in analyzing the net effect of the forces by isolating the object from its environment. An arrow pointing in the direction of a force represents a force and its magnitude is also labeled. FBDs allow systematic application of Newton's laws and hence are crucial in solving mechanics problems. For example on an inclined plane, in a block, the FBD helps identify normal, gravitational, and frictional forces acting on the block.
