What factors affect projectile motion?
FACTORS AFFECTING PROJECTILE MOTION There are three main factors that affect the trajectory of an object or body in flight: the projection angle, magnitude of projection velocity and height of projection.
What are some examples of projectile motion in your everyday life?
The following are a few common examples of projectile motion in real life.
- A football kicked in a game.
- A cannonball fired from a cannon.
- A bullet fired from a gun.
- A disc thrown in the sport of discus throw.
- The flight of a golf ball.
- A jet of water escaping a hose.
What are three types of projectiles?
Three types of projectiles— the bullet, the round ball, and shot—are used in muzzleloaders.
What are the applications of projectile motion?
Projectile motion refers to the motion of an object projected into the air at an angle. A few examples of this include a soccer ball begin kicked, a baseball begin thrown, or an athlete long jumping. Even fireworks and water fountains are examples of projectile motion.
Why is projectile motion important?
The projectile motion emphasizes one important aspect of constant acceleration that even constant acceleration, which is essentially unidirectional, is capable to produce two dimensional motion. The basic reason is that force and initial velocity of the object are not along the same direction.
What is the importance of projectile motion in sports?
DIVING. Inertia plays an important role in projectile motion, because it explains why an object keeps moving without any source of propulsion. There is also a force at play: gravity. Gravity explains why the soccer ball in the above example returns to Earth, rather than moving continuously through the air.
What are the two components of projectile motion?
There are the two components of the projectile’s motion – horizontal and vertical motion. And since perpendicular components of motion are independent of each other, these two components of motion can (and must) be discussed separately.
What is the difference between projectile motion and trajectory?
The path that the object follows is called its trajectory. Projectile motion only occurs when there is one force applied at the beginning, after which the only influence on the trajectory is that of gravity.
What kind of sports use the concept of projectile motion?
A projectile is anybody which is thrown or jumped into the air. Once it has left the ground it will follow a flight path called a parabola until it once more comes back down to earth. This applies to balls, javelins, discus, long jumpers, high jumpers, and horses showjumping.
Why do projectiles move in a curved path?
Air resistance and gravity are the only forces acting on a projectile. The combination of an initial forward velocity and the downward vertical force of gravity causes the ball to follow a curved path.
How does the angle affect projectile motion?
Higher launch angles have higher maximum height The maximum height is determined by the initial vertical velocity. Since steeper launch angles have a larger vertical velocity component, increasing the launch angle increases the maximum height.
How is satellite motion related to projectile?
satellite is a projectile. Second, a satellite is acted upon by the force of gravity and this force does accelerate it towards the Earth. In the absence of any forces whatsoever, an object in motion (such as a satellite) would continue in motion with the same speed and in the same direction.
What is the motion of satellite?
At just the right speed, it will move around the Earth in a circular motion. This type of motion and the path that a satellite moves in is called an orbit. Close to the Earth at an altitude of 100 km, a satellite needs to be moving at 8 kilometres per second (28 000 km/h) to stay in orbit.
What happens if a satellite slows down?
If the satellite slows down it would crash into the object it is orbiting. If the satellite speeds up, it may spin off into space. The satellite could be knocked or moved closer or farther from the object it is orbiting. The satellite could dip into the atmosphere of a planet and be slowed by that.
What is the principle of launching a satellite?
The fundamental principle to be understood concerning satellites is that a satellite is a projectile. That is to say, a satellite is an object upon which the only force is gravity. Once launched into orbit, the only force governing the motion of a satellite is the force of gravity.
What are the 4 types of satellites?
Types of Satellites and Applications
- Communications Satellite.
- Remote Sensing Satellite.
- Navigation Satellite.
- Geocentric Orbit type staellies – LEO, MEO, HEO.
- Global Positioning System (GPS)
- Geostationary Satellites (GEOs)
- Drone Satellite.
- Ground Satellite.
Do satellites need fuel?
A satellite orbiting closer to the Earth requires more velocity to resist the stronger gravitational pull. Satellites do carry their own fuel supply, but unlike how a car uses gas, it is not needed to maintain speed for orbit.
Why is it important to study the satellites?
NASA satellites help scientists study Earth and space. Satellites looking toward Earth provide information about clouds, oceans, land and ice. All this information helps scientists predict weather and climate.
How many dead satellites are in space?
3,000 dead
Can a satellite stay in orbit forever?
If the satellite was moving through empty space it would stay in its orbit forever, there being no forces acting to speed it up or to slow it down. In reality low orbit Earth satellites are not travelling through empty space and so experience a resistive force or drag due to the thin atmosphere which they encounter.
What affects the speed of a satellite?
As seen in the equation v = SQRT(G * Mcentral / R), the mass of the central body (earth) and the radius of the orbit affect orbital speed. The orbital radius is in turn dependent upon the height of the satellite above the earth. 2.
