# Why does gravitational acceleration differ at different places earth

### Why gravitational acceleration is different in different places on Earth?

Changes with time. The

**gravitational**potential at the surface of**Earth**is due mainly to the mass and rotation of**Earth**, but there are also small contributions from the distant Sun and Moon. As**Earth**rotates, those small contributions at any one place**vary**with time, and so the local value of g varies slightly.### How does the acceleration of gravity vary on Earth?

**Gravity**on the

**Earth’s**surface

**varies**by around 0.7%, from 9.7639 m/s

^{2}on the Nevado Huascarán mountain in Peru to 9.8337 m/s

^{2}at the surface of the Arctic Ocean.

### Why acceleration due to gravity is not same at all places?

**No**, the value

**of**g is different at different

**places**on the surface

**of**earth.

**Due**to which the radius

**of**the earth is smaller at poles and is larger at equator. therefore the

**acceleration due to gravity**is smaller at equator than that at poles.

### How does gravitational acceleration vary with different heights?

The

**acceleration**of an object changes with**altitude**. The change in**gravitational acceleration**with distance from the centre of Earth follows an inverse-square law. This means that**gravitational acceleration**is inversely proportional to the square of the distance from the centre of Earth.### Does g increase with height?

Variation of g with Height

This is the acceleration due to gravity at a height above the surface of the earth. Observing the above formula we can say that the **value of g decreases with increase in height of** an object and the value of g becomes zero at infinite distance from the earth.

### Does acceleration increase with height?

**Acceleration**is directly proportional to the

**height**of the object.

### Where is acceleration due to gravity is maximum?

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**.### Does force affect acceleration?

The acceleration of an object

**depends directly upon the net force acting upon the object**, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.### What is the acceleration of the ball at its maximum height?

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.

Variable | Value |
---|---|

a | -9.8 m/s^{2} |

t | 0.40 s |

### What is the acceleration of the ball after 1 second?

Answer Expert Verified

So after one second, the acceleration of the ball is **9.8 m/s²** and its velocity is 9.8 m/s. When you throw the ball upward, that acceleration is still 9.8 m/s².

### At what other angle should a ball be hit to reach the same distance?

Answer Expert Verified

Trajectories at 60° and 30° **angle** will have the **same distance** if they have the **same** initial velocity. 45° **angle** will **reach** the highest range if given the **same** initial velocity.

### What will be the velocity and acceleration of ball upward at maximum height?

Therefore,

**velocity**at the top is zero and**acceleration**is**acceleration**due to gravity (g).### Does throwing an object down increase acceleration?

The velocity of an object increases when we drop it down. This indicates that

**the object accelerates**. This is due to the attractive force of gravity. The value of g varies over the earth because the earth is not a perfect sphere and because of the rotation of the earth.### What is the acceleration of a rock thrown straight upward on the way up?

What is the

**acceleration of a rock thrown straight upward on the way up**? At the top of its flight? On the**way down**? The**acceleration**of the**rock thrown upward**has the same value of – 9.8 m/s^2 downwards at all three points of the**rock**on**way up**, stationary at the top of its flight and on**way down**.### What is the final velocity of the ball?

The

**ball**moves up to a maximum point, then reverses and falls to the ground. The**final velocity of the ball**is v_{f}= -14.7 m/s, taking down to be the negative direction.### Is V initial or final velocity?

It is represented by letter u. Three initial velocity formulas based on equations of motion are given below, If time, acceleration and velocity are known. The initial velocity is formulated as.

Formulas for Initial Velocity.

u | Initial velocity |
---|---|

v | Final Velocity |

t | time taken |

s | displacement |

a | acceleration |

### Can initial velocity be zero?

Well

**if an object starts from rest then it’s initial velocity would be zero**however if it is already in motion then it does have an initial velocity of greater than zero.### What is the symbol used for acceleration initial velocity and final velocity?

The

**symbol**a stands for the**acceleration**of the object. And the**symbol**v stands for the**velocity**of the object; a subscript of i after the v (as in v_{i}) indicates that the**velocity**value is the**initial velocity**value and a subscript of f (as in v_{f}) indicates that the**velocity**value is the**final velocity**value.### What are the 5 equations of motion?

In circumstances of constant acceleration, these simpler equations of motion are usually referred to as the “SUVAT” equations, arising from the definitions of kinematic quantities:

**displacement (S), initial velocity (u), final velocity (v), acceleration (a), and time (t).**### What is the relationship between velocity and acceleration?

Velocity is the rate of change of position with respect to time, whereas

**acceleration is the rate of change of velocity**. Both are vector quantities (and so also have a specified direction), but the units of velocity are meters per second while the units of acceleration are meters per second squared.### What is symbol of initial velocity?

The

**symbol**v_{0}[vee nought] is called the**initial velocity**or the**velocity**a time t = 0. It is often thought of as the “first**velocity**” but this is a rather naive way to describe it.### What does U mean in velocity?

u is

**initial velocity in m/s**. t is time in s. For example, a car accelerates in 5 s from 25 m/s to 3 5m/s. Its velocity changes by 35 – 25 = 10 m/s.### What are the 4 equations of motion?

They are often referred to as the SUVAT

**equations**, where “SUVAT” is an acronym from the variables: s = displacement, u = initial velocity, v = final velocity, a = acceleration, t = time.
