h=hmax. Putting the above values in equation (2), 0=(usinθ)2−2ghmax. ⇒(usinθ)2=2ghmax.

h = v 0 y 2 2 g . This equation defines the maximum height of a projectile above its launch position and it depends only on the vertical component of the initial velocity.

The maximum height of the object is the highest vertical position along its trajectory.

Free fall means that an object is falling freely with no forces acting upon it except gravity, a defined constant, g = -9.8 m/s2. The distance the object falls, or height, h, is 1/2 gravity x the square of the time falling.

Question: A ball thrown vertically upward reaches a maximum height of 30 meters above the surface of Earth. At its maximum height, the speed of the ball is: Answer: 0 m/s. The instantaneous speed of any projectile at its maximum height is zero….Objects Launched Upward.

(a) What are its velocity and acceleration when it reaches its maximum altitude? Key: At the maximum height, the ball is momentarily at rest. (That is, it has zero velocity.) The acceleration remains constant, with magnitude equal to the free-fall acceleration and directed downward.

Therefore, velocity at the top is zero and acceleration is acceleration due to gravity (g).

For an object placed at a height h, the acceleration due to gravity is less as compared to that placed on the surface. As depth increases, the value of acceleration due to gravity (g) falls.

Where, g is the acceleration due to gravity on the surface of the earth. g’ = g Thus acceleration due to gravity is least at the equator and maximum at the poles.

The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s.

When an object falls freely towards the surface of the earth from a certain height, then its velocity changes. This change in velocity produces acceleration in the object which is known as acceleration due to gravity denoted by the letter g. The value of acceleration due to gravity is g= 9.8 m/s2.

The acceleration which is gained by an object because of gravitational force is called its acceleration due to gravity. The acceleration due to gravity at the surface of Earth is represented by the letter g. It has a standard value defined as 9.80665 m/s2 (32.1740 ft/s2).

Acceleration: It is a measure of the change in the velocity of an object per unit time. Acceleration can be caused either by change in direction of motion or change in speed or both.

Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2. When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location.

Value of g

1. G is the universal gravitational constant, G = 6.674 x 10-11 m3 kg-1 s-2.
2. M is the mass of the body measured using kg.
3. R is the mass body radius measured by m.
4. g is the acceleration due to the gravity determined by m / s2.
