Weird Wonderful Water

Weird Wonderful Water

Life in the Sea

This programme is about seawater. It is the most important liquid on Earth, not only from its sheer volume, but also because it has remarkable qualities. A few of them, like buoyancy, are common to all liquids - but seawater is also the cradle of...Show More
Uniform Circular Motion

Uniform Circular Motion

Motion

When an object moves along a circular path at a constant speed, its motion is called uniform circular motion. Uniform circular motion is an accelerated motion.
Rest and Motion

Rest and Motion

Motion

A body is said to be in a state of rest if its position does not change with respect to a reference point with the passage of time, and a body is said to be in a state of motion if its position changes with respect to a reference point with the...Show More
The Mechanical Advantages of Inclined Planes

The Mechanical Advantages of Inclined Planes

Understanding Structures and Mechanisms: Systems in Action

In an inclined plane, the mechanical advantage is the length of the slope divided by the height of the inclined plane. The mechanical advantage of a wedge is determined by dividing the length of the wedge by its width. The mechanical advantage of...Show More
The Mechanical Advantages of a Lever

The Mechanical Advantages of a Lever

Understanding Structures and Mechanisms: Systems in Action

A lever is a rigid bar that is free to rotate or pivot on a fixed point called a fulcrum. In the case of a lever, we increase the input distance. The ideal mechanical advantage is calculated by dividing the distance from the fulcrum to the...Show More
Acceleration

Acceleration

Motion

The rate of change in the velocity of a body with respect to time is called acceleration. Depending upon the change in velocity, the acceleration in a body can be positive, negative, uniform, non-uniform, or zero.
Uses of Convex Mirror

Uses of Convex Mirror

Light and Geometric Optics

The convex mirror is used in rear-view mirrors in vehicles because it forms an erect and smaller image of the scene behind the vehicles. Convex mirrors are used in street lights and in shops, big supermarkets, and other places as anti - theft...Show More
