    Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F {tex}\times{/tex} d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work.

    Free fall is the term used when we do not appy any external force to any body to fall on the earth. Eg. Dropping a stone from a roof . Gravity is said when we apply some external force to any body to make it fall on earth and the object is attracted by earth due to gravity . Eg. Throwing a stone from ground to a certain height and then coming of the stone back to the earth due to gravity

    Yogita Ingle 5 years, 11 months ago

    • A molecule is a collection of various atoms that combine chemically with each other.

    • These atoms are bound together by certain forces of attraction.

    • Atoms of the same elements or different elements can bind together to form molecules.

    • Therefore, a molecule is the smallest particle of a substance that can exist independently and shows all the properties of that substance.

    Conservation of law of momentum means when the sum of two objects before collision is equal to the sum of momenta after the collision provided, there is no external unbalance force is known as law of conservation of momentum..

    2Thank You

    Somanath Nayak 5 years, 11 months ago

    Conservation of momentum is a fundamental law of physics which states that the momentum of a system is constant if there are no external forces acting on the system. It is embodied in Newton's first law (the law of inertia).
