Kinematics
A machine is a device that accepts energy in some available form and utilizes it to do a type of work. Energy, work, or power has to be transferred from one mechanical part to another to run a machine. While the transfer of energy between two machine parts, those two parts experience a relative motion with each other. Studying such relative motions is termed kinematics.
Kinetic Energy and Work-Energy Theorem
In physics, work is the product of the net force in direction of the displacement and the magnitude of this displacement or it can also be defined as the energy transfer of an object when it is moved for a distance due to the forces acting on it in the direction of displacement and perpendicular to the displacement which is called the normal force. Energy is the capacity of any object doing work. The SI unit of work is joule and energy is Joule. This principle follows the second law of Newton's law of motion where the net force causes the acceleration of an object. The force of gravity which is downward force and the normal force acting on an object which is perpendicular to the object are equal in magnitude but opposite to the direction, so while determining the net force, these two components cancel out. The net force is the horizontal component of the force and in our explanation, we consider everything as frictionless surface since friction should also be calculated while called the work-energy component of the object. The two most basics of energy classification are potential energy and kinetic energy. There are various kinds of kinetic energy like chemical, mechanical, thermal, nuclear, electrical, radiant energy, and so on. The work is done when there is a change in energy and it mainly depends on the application of force and movement of the object. Let us say how much work is needed to lift a 5kg ball 5m high. Work is mathematically represented as Force ×Displacement. So it will be 5kg times the gravitational constant on earth and the distance moved by the object. Wnet=Fnet times Displacement.

The graph of U(x) is labelled for 8 positions of the particle.
Answer True, False, or Cannot tell to each of the statements below; e.g., if the first statement is true and the rest, cannot tell, enter TCCCCC.
i. If the particle is located slightly to the left of position 2, the force on the particle is directed to the right.
ii. The slope of U(x) is positive when the particle is located at position 1, so the force on the particle is to the right.
iii. The net force on the particle is zero when it is located at position 4; this is a point of stable equilibrium.
iv. A point of stable equilibrium is one in which small deviations from the equilibrium point will create a force that accelerates the particle away from the equilibrium point.
v. The force on the particle at position 7 is directed to the left.
vi. The magnitude of the net force on the particle is a minimum when it is at position 8.
