If thrown directly upwards, it slows down due to gravitational attraction and aerodynamic drag. It reaches a maximum height and then falls. Its rate of descent is accelerated by the earth's gravity but decelerated by aerodynamic drag. If thrown at an angle, it follows a trajectory in which the vertical motion is accompanied by horizontal motion which is decelerated by aerodynamic drag.
If you disregard drag, then the vertical motion is symmetrical: at any height the speed going up is exactly the same as the speed on descent. Also, for a body thrown at an angle, the trajectory is a parabola.

Why does newton's first law of motion not work on earth?
It sure works on Earth. It works everywhere. If there is no net force on an object, the object will not accelerate. Vice versa, if the object does not accelerate, that means there is no net force on the object.
Is an object that is not moving relative to Earth a blue shift?
No, an object that is not moving relative to Earth does not experience a blue shift. A blue shift occurs when an object is moving towards an observer, causing the light waves to be compressed and appear bluer.
What object does the earth orbit?
The Earth orbits around the Sun. This motion is what creates our year as the Earth completes a full orbit approximately every 365 days.
A body can escape the gravitational pull of the earth if it is thrown up with a velocity of?
In order for a body to escape the gravitational pull of the Earth, it needs to be thrown up with an initial velocity equal to or greater than the escape velocity of around 11.2 km/s. This velocity allows the object to overcome the gravitational pull of the Earth and continue traveling away from it indefinitely.
What is the difference between an orbit a revolution and a rotation?
An orbit and a revolution are roughly the same thing as the Earth orbits or revolves around the sun, and the moon around the Earth. Rotation refers to the spinning of the celestial being. Earth for example, rotates every 24 hours.
True or false the motion of an object thrown at an angle is projectile motion?
True. Projectile motion describes the curved path an object follows when thrown or projected near the Earth's surface, under the influence of gravity, while also moving horizontally.
What is the downward acceleration of a thrown object in projectile motion?
The downward acceleration of a thrown object in projectile motion is constant and equal to the acceleration due to gravity, which is approximately 9.81 m/s^2 on Earth. This acceleration acts vertically downward and affects the vertical motion of the object while the horizontal motion remains unaffected.
What type of motion is exhibited by a ball thrown up from the surface of earth?
The motion exhibited by a ball thrown up from the surface of the Earth is projectile motion. It has both vertical and horizontal components, with the vertical motion affected by gravity and the horizontal motion continuing at a constant velocity (neglecting air resistance).
Why motion of body thrown from a certain height?
The motion of a body thrown from a certain height can be described by the laws of projectile motion, where the object follows a curved path due to the combination of its initial velocity and the force of gravity. As the object moves through the air, it experiences acceleration towards the Earth, resulting in a parabolic trajectory until it eventually reaches the ground.
What is the curved path an object takes when it is thrown?
The curved path an object takes when it is thrown is called a projectile motion. It is influenced by both the initial velocity of the object and the force of gravity acting on it. The shape of the path is typically parabolic.
How do you find motion?
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.
Why every object falls downward while thrown up?
Every object falls downward when thrown up due to the force of gravity. Gravity is a fundamental force that pulls objects towards the center of the Earth. When an object is thrown up, gravity acts to slow down and eventually reverse its motion, causing it to fall back towards the ground.
An object is in motion if its position changes relative to a what?
An object is in motion if it changes position relative to a reference point. Motion is a relative quantity and is expressed in respect to the position of another object. Example: both a car and the Earth are moving (earth is revolving around the sun) but if we express the motion of the car in respect to the Earth, we say the car is moving relative to the Earth. At the same time the earth is moving relative to the sun.
What's a Projectile motion?
Projectile motion refers to the movement of an object through the air when only the force of gravity is acting upon it. The object is typically projected at an angle to the ground and follows a curved path. The motion can be described using equations that take into account the initial velocity, angle of projection, and acceleration due to gravity.
How do you find projectile motion?
To find the projectile motion of an object, you can use the equations of motion for horizontal and vertical components. The horizontal motion is constant, while the vertical motion is affected by gravity. By determining the initial velocity, angle of projection, and acceleration due to gravity, you can calculate various parameters like range, maximum height, and time of flight.
Motion that is under the influence of gravity alone is called?
Free fall is the term in Newtonian physics used to describe the motion of an object under the influence of gravity alone. Such an object moves along a geodesic. One example of an object always in free fall is Earth's moon.
Which word is used to describe the motion of the earth as it circles another object in space?
Orbit is the word used to describe the motion of the Earth as it circles another object in space.
