Area
The surface area represents a physical size of a body that is obtained by multiplying its length and width. Before calculating the surface area, it is necessary to measure the length and width of the rectangles. If it's a...
Gravitational Interaction
Gravity is an invisible force that draws all the bodies in the Universe to each other. Solar gravity keeps the planets in their orbits. Earth's gravity 'ensures' that the Moon circulates in its orbit around the Earth. The...
Third Newton's law is often called the Law of Action and Reaction. And the law explains the nature of force between two interaction bodies that have equal magnitude and the opposite directions.
If the force comes from one body and...
The figure shows the axis of the traveled path and the value of time in seconds.
During the movement of cars we measure the length of the road (distance) and the time of movement.
When we apply the time expressed in...
