The flow is the time derivative of the water in the bucket. The basic ideas are not more difficult than that. Calculus analyses things that change, and physics is much concerned with changes. For physics, you'll need at least some of the simplest and most important concepts from calculus.
Chapter 4 Kinematics (Class XI)
Kinematics, branch of physics and a subdivision of classical mechanics concerned with the geometrically possible motion of a body or system of bodies without consideration of the forces involved (i.e., causes and effects of the motions).
Chapter 5 Laws Of Motion (Class XI)
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Chapter 6 Work Energy & Power With Circular Motion (Class XI)
WORK, ENERGY AND POWER. Work can be defined as transfer of energy. In physics we say that work is done on an object when you transfer energy to that object. If one object transfers (gives) energy to a second object, then the first object does work on the second object.
Chapter 8 Heat And Thermodynamics (Class XI)
Thermodynamics is a branch of physics concerned with heat and temperature and their relation to other forms of energy and work. The behavior of these quantities is governed by the four laws of thermodynamics, irrespective of the composition or specific properties of the material or system in question.
Rotational Motion of a Rigid Body. ... A rigid body is an object with a mass that holds a rigid shape, such as a phonograph turntable, in contrast to the sun, which is a ball of gas. Many of the equations for the mechanics of rotating objects are similar to the motion equations for linear motion.
Chapter 9 Fluid Statics And Dynamics (Class XI)
Fluid Statics and Fluid Dynamics form the two constituents of Fluid Mechanics. Fluid Statics deals with fluids at rest while Fluid Dynamics studies fluids in motion. ... A fluid at rest has no shear stress. Consequently, any force developed is only due to normal stresses i.e, pressure.
Chapter 10 Gravitation (Class XI)
Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.
Chapter 11 SHM & Elasticity (Class XI)
In mechanics and physics, simple harmonic motion is a special type of periodic motion or oscillation motion where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of displacement.
In physics, elasticity (from Greek ἐλαστός "ductible") is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed. Solid objects will deform when adequate forces are applied on them.
Chapter 12 Waves (Class XI)
In physics, a wave is an oscillation accompanied by a transfer of energy. Frequency refers to the addition of time. Wave motion transfers energy from one point to another, which displace particles of the transmission medium–that is, with little or no associated mass transport. ... There are two main types of waves
Chapter 13.System Of Particles (XI)
Under certain circumstances the linear momentum of a system is conserved. The linear momentum of a particle is related to the net force acting on that object: ... " The linear momentum of a system of particles is equal to the product of the total mass M of the system and the velocity of the center of mass.
