Forces measured in Newton. It’s a vector quantity
Gravitational force or gravity or (on Earth) Weight.
Frictional force or friction
Air resistance or drag.
Buoyant force or upthrust.
The force from A on B.To act, to push, to pull
upwards , downwards ¯, forwards ®, backwards¬, towards something.
the upward force (upwards: adverb, upward adjective)Accelerated or uniform motion
Linear motion is movement in a straight line
Uniform speed (velocity = speed as a vector): the speed of the object is constant
Circular motion: the trajectory is a circle.
Inertia is the tendency of an object to resist a change of velocity.The principle of Inertia or Newton’s first Law of motion:
If the forces on a mass are balanced (no resultant force), then:- If it is at rest, it stays at rest.
- If it is moving, it keeps on moving at a constant speed in a straight line.

The technology described in the video, which focuses on the electronic photo finish technology used in horse racing at Woodbine, is not directly used in the Olympic Games. The technology used in horse racing and track and field events, including the Olympics, may share some similarities, but they are typically distinct systems.
In the Olympics and other major athletic competitions, high-speed cameras are commonly used for photo finishes. These cameras capture a rapid series of images as athletes cross the finish line, allowing officials to determine the precise order of finish in races. The principles of capturing a specific moment in time and analyzing the images for accurate results are similar, but the implementation may vary.
While the specific details of the technology used in horse racing and athletics can differ, the overarching goal is to provide accurate and fair results in sporting events. Each sport may adopt technology tailored to its unique characteristics and requirements.- Ouvert le : jeudi 18 janvier 2024, 00:00À remettre : samedi 25 janvier 2025, 00:00
