 # JC 1 Physics (A-level) Tuition Lesson

### Rotational Equilibrium

In this video lesson, our JC1 Physics PMC tutor explains the concept of rotational equilibrium. Rotational equilibrium is defined as the state of a system for which the total angular acceleration is zero.

### Kinematics Physics Equations Explained

Kinematics is the study of objects in motion and their inter-relationships. There are four kinematic equations which relate to displacement, D, velocity, v, time, t, and acceleration, a. In this video, our JC1 Physics PMC tutor can clear your doubts on the different equations.

### Conservation of Momentum in Collisions

Our JC1 Physics PMC tutor goes through the conservation of momentum in collisions in this lesson. The law of momentum conservation is one of the most powerful laws in physics which states that a measurable property of an isolated physical system does not change as the system evolves over time.

### Newton’s Second Law of Motion

Newton’s second law of motion states that 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. In this lesson, our JC1 Physics PMC tutor explains the approach to questions where this concept is to be applied.

### Conservation of Energy and Circular Motion Example Problem

This video follows through our JC1 Physics PMC tutor’s explanation of how to attempt questions on circular motion and conservation of energy. Circular motion is a movement of an object along the circumference of a circle or rotation along a circular path while the law of conservation of energy states that the total energy of an isolated system remains constant and is said to be conserved over time.

### Resultant Gravitational Field Strength Example Problem

In this video lesson, our JC1 Physics PMC tutor breaks down the steps to answering questions on gravitational field strength. Gravitational field strength at a point is the gravitational force exerted per unit mass placed at that point.
