The Effect Of Projectile Motion On The Force Of Gravity

Science Olympiad is set up as a competition in the same way a track competition is set up. Competitors extensively train for each of their events for several months beforehand in order to perform well on competition day. There are 23 events that cycle through each year to accurately represent the scientific challenges society faces today. For example, there are many events for renewable energy or eco-friendly technology in response to the ever growing threat of global warming. These events such as wind power or electric vehicle would be considered build events as they require hands on experience to build well thought-out

Newton 's three laws of motion play a huge role in our everyday life; from driving down the road and catching a baseball. Newton’s laws help us fully understand gravity, motion, and force in three easy-to-understand laws.

As the kicker steps forward and swings his/her leg back and then forward, contact with the football is made. The kicker kicks the football with the intention of the ball making it through the goal posts, which would result in either one (for an extra point) or three points (for a field goal). The kick is another example of a force. A great force is exerted on the football, causing it to accelerate and travel a distance (Newton’s first law of motion). Also, the football exerts the same force back on the kicker’s foot (Newton’s third law of motion). The kicker tries to kick the football about one-third of the way up the football (towards the bottom) so that the ball will travel high enough to get over the defense and high enough to maximize the distance. When the kicker hits the football, it is another example of an inelastic collision in which some of the energy is transformed into sound. The flight of the football can be described as projectile motion.

the planets fall around the Sun. Each of these objects balances the Sun 's force of gravity

The Earth revolves around the sun due to the gravitational force between them, so the Earth is pulled by the gravitation between it and the Sun. The Sun moves in an orbit as well due to the same gravitational force between it and the planet, which is the same as in real life. Also, the Moon revolves around the Earth like the moon revolves around the planet. It can be observed that the moon moves faster when the planet (Earth) is closer to the sun. This can be confirmed using Kepler’s Second Law (Equal Areas) because it states that the speed of the planet constantly changes and becomes faster when it is closer to the sun because it is in an elliptical

In 1916 Einstein proposed his new General Theory of Relativity that built upon Newton's Universal Theory of Gravitation which showed "that gravity is responsible for the motions of both planets and falling objects near the Earth" (Fix, p 86). Einstein' theory "describes gravity as a curvature in four-dimensional spacetime" (Singh, p. 502). The original intent of the theory was to explain the inaccuracies of Mercury's orbit when using Newton's law and the Sun's bending of light.

__A__ 1. The weight of an object is a. a measure of the gravitational force pulling the object toward the earth. b. equal to the mass of the matter in the object. c. a measure of the space occupied by the object. d. the same at any location on the earth.

Some of these factors are gravity, the air resistance, the speed of release, the angle of release, and the height of release. The most basic and principal factor acting on a projectile is gravity. Gravity affects every object. It decreases the height that a projectile can attain. Air resistance is also a key factor working on an object. The larger the surface area, the more air resistance will affect a projectile. Air resistance will also affect an object more if it has a smaller mass. Also, the faster the speed of the projectile, the greater the air resistance. The speed of release refers to how fast an object is released and is directly related to the distance of the flight. The greater the speed of release and object has, the greater the distance the object will have. The initial vertical velocity increases the height of trajectories, creating a longer flight path. Similarly, as the initial horizontal velocity increase, the longer the length of flight and distance. The angle of release is the angle that an object is thrown or hit into the air. It changes the relationship

When the ball hits the ground the ball deforms and the air pressure increases in the deformed area and quickly through all the ball

Many athletes use basketballs, soccer balls, and volley balls to play their sports. The balls need to have the right temperature and air pressure inside in order to work best. When a ball drops gravity pulls it down to the ground. After the ball hits the floor the ball gains motion that is

While watching a person tumble it is easy to see why projectile motion has a very big role in tumbling. Projectile motion is the form of motion in which an object falls towards earth after being thrown. Projectile

Trajectory – moving in or representing straight lines, arches or curves or the movement of objects through the air.

Before Newton talked about gravitation the main knowledge of scientists was a elementary knowledge of optics, mechanics and astronomy.Copernicus Kepler and Galileo provided the background knowledge of the stars and planets, but Newton used their data to discover the whole gravitational system.10Newton reasoned that the planets and all other physical objects in the universe moved through mutual attraction of gravity.Newton said that every other object in the universe affected every other object through gravity.This explained why the planets move in an orderly fashion. Newton found that “the force of gravity towards the whole planet did arise from and was compounded of the forces of gravity towards all it’s parts, and towards every one part was in the inverse proportion of the squares of the distances from this part.”Newton proves all of this mathematically. This was known to be the single most important contribution to physics that ever has been made.11

The gravitational acceleration, or gravitational field strength, which is denoted by g, refers to the acceleration that the Earth imparts to objects on or near its surface due to gravity. It has an approximate value of 9.8 m/s2; however, other factors such as the rotation of the Earth also contribute to the net acceleration. The precise strength of Earth's gravity varies depending on location. The nominal "average" value at the Earth's surface is 9.80665 m/s.

When receiving a pass you catch or slow the balls momentum to zero, which is called impulse, the interaction that changes an object’s momentum-a force acting for a time interval (Kirkpatrick Wheeler 107). This is shown in an equation form
