The acceleration on a projectile as it comes down is approximately equal to the acceleration due to gravity, which is 9.81 m/s^2 on the surface of Earth. This acceleration acts in the downward direction and causes the projectile to increase in velocity as it falls towards the ground.
The minimum speed for a projectile to achieve orbit around the Earth, known as orbital velocity, is approximately 17,500 miles per hour (28,000 kilometers per hour) when launched from the Earth's surface. This speed allows the projectile to balance the pull of gravity with the force of its forward motion, resulting in a stable orbit.
The minimum initial speed for a projectile to escape Earth's gravitational pull (escape velocity) is about 11.2 km/s. This speed is independent of the mass of the projectile and is based on the balance between the projectile's kinetic energy and gravitational potential energy. Any speed greater than the escape velocity will allow the projectile to escape Earth's gravitational pull.
The horizontal component of a projectile's velocity doesn't change, until the projectile hits somethingor falls to the ground.The vertical component of a projectile's velocity becomes [9.8 meters per second downward] greatereach second. At the maximum height of its trajectory, the projectile's velocity is zero. That's the pointwhere the velocity transitions from upward to downward.
Yes, the vertical motion of a projectile is accelerated due to the force of gravity acting on it, pulling it downward towards the Earth. This acceleration is constant and equal to the acceleration due to gravity, which is approximately 9.81 m/s^2 on Earth.
A projectile that continually falls around Earth is called a satellite. These objects are thrown into orbit around the planet and their speed is balanced by the force of gravity, allowing them to constantly fall towards Earth while also moving sideways fast enough to stay in orbit.
The path of a projectile in earth gravity is that of a parabola.
The projectile must be traveling fast enough to avoid falling into the earth's atmosphere but slow enough to avoid escaping the earth's gravitational pull.
The acceleration on a projectile as it comes down is approximately equal to the acceleration due to gravity, which is 9.81 m/s^2 on the surface of Earth. This acceleration acts in the downward direction and causes the projectile to increase in velocity as it falls towards the ground.
Projectile motion is a form of motion in which a projectile is thrown near the earth's surface. When thrown, the projectile moves along a curved path because of gravity. An example of projectile motion is a sprinkler shooting water into the air and the water falling back down to Earth.
acceleration remains the same
the moon or satelite
The Earth. Actually, technically, the Moon and Earth revolve around a common center of gravity, but that center of gravity falls within the earth itself.
Satellites are in constant free-fall. This simply means they are constantly being accelerated by earth's gravity. However, an orbiting satellite's lateral motion is sufficient that the acceleration caused by the earth's gravity causes it to continually circle the earth, instead of crashing to the ground.
The minimum speed for a projectile to achieve orbit around the Earth, known as orbital velocity, is approximately 17,500 miles per hour (28,000 kilometers per hour) when launched from the Earth's surface. This speed allows the projectile to balance the pull of gravity with the force of its forward motion, resulting in a stable orbit.
. The speed of the satellite is adjusted so that it falls to earth at the same rate that the curve of the earth falls away from the satellite. The satellite is perpetually falling, but it never hits the ground!
Acceleration at the point of zero vertical velocity will be equivalent to gravitational acceleration on that body. On Earth, for example, this is around 9.8 meters per second per second (9.8m/s2).
