What is work done by gravity if object thrown at certain angle to ground moved a curved path n falls back to the ground initial and final position of objects path lie on the same horizontal line?
Knowhunt
It depends on the angle, the speed of the throw, and the mass of the object.
Surprisingly, it doesn't depend on the acceleration of gravity.
' A ' is the angle of the throw above horizontal
' V ' is the speed of the throw
' M ' is the mass of the object
The work done by gravity is:
1/2 M [ V sin(A) ]2

An aeroplane flying at a constant velocity releases a bomb. As the bomb drops down from the aeroplane what will be the position of the bomb with respect to the plane?
There are two forces on the bomb when it is dropped; horizontal, and vertical. The vertical force is gravity, and the horizontal force is the velocity of the plane when the bomb is dropped. In order to determine how far away the bomb will drop from the initial point of release, it is necessary to know the height that the plane is at, and the velocity of the plane, which is also the initial horizontal velocity of the bomb (it is constant, neglecting air resistence.)
A projectile is thrown with an initial velocity which has a horizontal component of 4 m s What will be its horizontal speed after 3s?
A projectile that is thrown with an initial velocity,that has a horizontal component of 4 m/s, its horizontal speed after 3s will still be 4m/s.
Why motion of body thrown from a certain height?
The body will move: * Because of its initial motion (the question states that it is thrown) * Because of gravity
What is the value of constant horizontal velocity?
In projectile motion, since , there's no force in the horizontal direction which can change the horizontal motion therefore the horizotal velocity remains conserved Vx=Vox= Vocos theta by using above formula , constant horizontal initial or final velocity can be found. since Initial = final horizontal velocity.

How do you calculate initial velocity given only the initial position and the scale of the horizontal and vertical axes?
We suspect that you're also given a line on the graph. If so, then the initial speed is the slope of the line at the initial position. To get the real slope of the line, you need to know the scales of the axes. If the scales aren't the same, then the real slope of the line isn't what it looks like, and has to be calculated by measuring its progress along both axes just after the initial position.
What is the initial position of the ball what is its final position?
The initial position is where it starts; the final position is where it ends up.
What is the initial position of the ball what is the final position?
The initial position is where it starts; the final position is where it ends up.
What initial is given to the horizontal axis?

How do you find vertical and horizontal components when given the initial velocity?
If the initial velocity is v, at an angle x to the horizontal, then the vertical component is v*sin(x) and the horizontal component is v*cos(x).

When can you say that a certain object is moving?
when an object shifts or is displaced from its initial position with or without acceleration then we can say that the object is moving.
