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.

Is an object that is not moving relative to Earth a blue shift?
No, an object not moving relative to Earth is not a blue shifted object. With no relative motion, an object will not be subject to Doppler effect and will not red or blue shift. For an object to be blue shifted, the distance between the object and Earth must be decreasing. The object must be closing on Earth or vice versa.
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.
A body can escape the gravitational pull of the earth if it is thrown up with a velocity of?
An object would need to start at about 25 miles per second in order to escape Earth's gravity.
Why does the Earth rotate in single direction?
Once an object, any object, such as the Earth, is set in motion to rotate in a particular direction, it will always continue to rotate in that direction. For the Earth to rotate in another direction would take an enormous, cataclysmic force that would have to be created by a gigantic object colliding with it, or at least coming very close to it.
How does the gravitational force on the surface of jupiter compares to the gravitational force on the surface of earth?
In jupiter , the value of g is 3 times more than earth. earth is the only planet where gravity is normal . Whereas on other planets the gravity is too much that no object can be thrown upward and on some planets , gravity is too less that no object after being thrown , will come downward. In jupiter the value of g is 25.93 m/s2 and on earth g is 9.8 m/s2
What's a Projectile motion?
Projectile motion is a form of motion in which an object or particle is thrown near the earth's surface, and it moves along a curved path.
What are Example of acceleration which is against direction of motion?
deceleration in a linear motion (braking during driving or an object thrown up while you are standing on on earth) --> the acceleration is pointing at an opposite direction than the motion. ============================
What type of motion is exhibited by a ball thrown up from the surface of earth?
An object thrown up from the surface of the Earth exhibits ballistic or projectile motion. Actually, it doesn't matter where it's "thrown" from; any object which accelerates only due to gravity follows a curve that's a conic section. This can be a circle, an ellipse, a parabola, or a hyperbola (technically, one branch of a hyperbola) depending on its initial velocity and starting position, and all of these are considered "ballistic" trajectories.
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.

What causes the speed of an object to decrease?
An object that is slowing down is moving or in motion until it stops.It is not necessarily accelerating, as an accelerating object will begin traveling in the opposite direction after it stops. For example, a ball thrown into the air will slow down as the force of the earth's gravity causes it to accelerate downwards. For an instant, the ball will be motionless before moving towards the earth.
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.
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.
What happens to household refuse?
It gets thrown into the landfills which pollutes the earth.
When an object's distance from another object is changing what is it called?
it depends on the reference points, that is form where the object is viewed...when sun is viewed form earth, it moving...but earth is also moving...when the rotation of the earth is stopped, then the sun is at a constant position...thereforean object position relative to another object is changingonly when the reference point changes..
What describes the motion of object's affected by gravity near Earth's surface?
Gravitational pull. Answer: The motion of a free falling object with or without lateral movement is a trajectory
What happens when a moving object encounters friction?
It transferrs from the moving object to the stationary object.
