LEARNING OBJECTIVE 3.A.1.1 - Express the motion of an object using narrative, mathematical, and graphical representations. AP MECHANICS -C LEARNING OBJECTIVE INT 2.C -Describe the direction of the velocity and acceleration vector for an object moving in two dimensions, circular motion One of the most interesting applications of Newton’s Law is to solve problems related to the motion of an...
AP MECHANICS -C LEARNING OBJECTIVE CON 1.A -. Describe the role of a conservative force or a dissipative force in a dynamic system. Does the work done by a conservative force depend upon the trajectory or path? Suppose a conservative force of constant magnitude F acts downwards. Under the influence of this force, an object moves along a curved path from point A to point B. How much work is done...
AP MECHANICS -C LEARNING OBJECTIVE CON 1.C -Describe the force within a system and the potential energy of a system. In the last section, we derived a relationship between force F(x) and potential energy U(x). In order to use the relationship, we will need to know the exact function of either U(x) or F(x) and then use calculus to obtain the other. In this section, we will take a visual approach...
AP MECHANICS -C LEARNING OBJECTIVE CON 1.B -Derive an expression that represents the relationship between a conservative force acting in a system on an object to the potential energy of the system using the methods of calculus. 1.F -Derive an expression for the gravitational potential energy of a system consisting of a satellite or large mass (e.g., an asteroid) and the Earth at a great distance...
AP MECHANICS -C LEARNING OBJECTIVE CON 1.C -Describe the force within a system and the potential energy of a system. So far we have seen that a potential energy function U(x) can be found in the cases where conservative forces are acting in the system. We proved that in such cases the work done by the forces in a closed loop is always zero. For a one-dimensional case where the U varies only as a...

In the last section, we derived an expression to calculate the numerical value of kinetic energy. Let’s now derive expressions for potential energy associated with two of the forces we will be frequently...
LEARNING OBJECTIVE 3.3.A - Describe the potential energy of a system. AP MECHANICS -C LEARNING OBJECTIVE CON 1.E -Calculate the potential energy of a system consisting of an object in a uniform gravitational field. In the last section, we derived an expression to calculate the numerical value of kinetic energy. Let’s now derive expressions for potential energy associated with two of the...
LEARNING OBJECTIVE 3.4.C - Describe how the selection of a system determines whether the energy of that system changes. AP MECHANICS -C LEARNING OBJECTIVE CON 1.A -Compare conservative and dissipative forces. Describe the role of a conservative force or a dissipative force in a dynamic system. In the last section, we looked at the case of motion of a ball in the gravitational field and concluded...
LEARNING OBJECTIVE 3.4.B - Describe the behavior of a system using conservation of mechanical energy principles. AP MECHANICS -C LEARNING OBJECTIVE CON 1.A -Compare conservative and dissipative forces. Describe the role of a conservative force or a dissipative force in a dynamic system. In last section, we looked at the law of conservation of mechanical energy. Then we quickly dismissed it in...
LEARNING OBJECTIVE 3.4.C - Describe how the selection of a system determines whether the energy of that system changes. AP MECHANICS -C LEARNING OBJECTIVE CON 2.A -. Describe physical situations in which mechanical energy of an object in a system is converted to other forms of energy in the system. An object thrown into the air with a certain kinetic energy returns to the ground without quite the...
Hi, I am Gaurav. I am a passionate physics student and tutor. I help students study and prepare for exams such as AP Physics, NEET and IIT JEE. I appeared for IIT JEE exam way back in 1998 and during that time I fell in love with Physics. I managed to clear the exam and eventually worked in several countries in different roles but the love for Physics always continued and hence the journey of life long learning and teaching.
