Physics differentiate the good from the great goalkeepers, and to be one of them you need to have in mind this four things: 

The Understanding of Momentum- A goalkeeper must keep his weight shifted forward, standing on the balls of his feet
he Analysis of Vectors- While preparing for a shot, a goalkeeper must analyze vectors at all times to determine where he should stand.
The Maximization of Impulse- the most expensive goalie gloves are made of the softest foam, with premium cushioning in the palms.
The Knowledge of Torque- The goalkeeper slides out on the grass, attacking the ball low.

When bicycles were first invented, they had a large front wheel with a large radius. This made them extremely efficient and fast to ride on flat spaces, but unfortunately they were quite unstable and therefore very dangerous to the rider. The center of mass was very high and the bike overturned easily.
Champion Tour de France cyclist Lance Armstrong, like many top cyclists, use technology to improve performance. Lance used a specially designed helmet for time trials. This is an event where maximum efficiency and speed is required. The helmet design helped to shave vital seconds of his time. The helmet minimizes friction by allowing air to flow over his head and down his back. An ordinary helmet would cause turbulent wind flow at his neck and create drag. He also wore specialized clothing to decrease drag.

Add some text, 
Knowledge about the physics of running is of particular interest to high-level athletes who strive to optimize their performance, using a combination of expert coaching and state-of-the-art training facilities. To most people, the physics behind running is hardly given a second thought. But when medals, such as Olympic medals, are on the line then such thoughts become commonplace and turn into active areas of research. 
When running, you need to have in mind: 
Force generated during running.
Path traveled by runner's center of mass.
Arm swinging.
Effect of race curve on running times.
Effect on track material on running times.

The physics behind curling a football

       “Bend it like Beckham” is the name given to the curled-ball effect, that name is given because of the English soccer legend, and model, David Beckham. Many people can curl the ball, but few of them know the physics behind the kick-and-curl. To curl the ball, you simply kick the ball slightly off the center of the ball, and a little downwards, causing it to spin horizontally. The air will move more quickly around one side, making less pressure on that side of the ball.
