What are the factors influencing acceleration due to gravity?
The value of acceleration due to gravity ‘g’ is affected by. Altitude above the earth’s surface. Depth below the earth’s surface . The shape of the earth. Rotational motion of the earth. Variation of g with Height. Acceleration due to Gravity at a height (h) from the surface of the earth
How does gravitational force affect acceleration?
Gravity lets all objects fall to the ground at the same speed, 9.8 m/s/s. If the force of gravity were stronger, such as 10 m/s/s, the rate of acceleration would be faster.
What rate does gravity cause objects to accelerate?
Gravity causes all objects to accelerate toward Earth at a rate of 9.8 m/s/s. Air resistance slows the acceleration of falling objects. An object falls at its terminal velocity when the upward force of air resistance equals the downward force of gravity.
How fast is acceleration due to gravity?
At Earth’s surface the acceleration of gravity is about 9.8 metres (32 feet) per second per second. Thus, for every second an object is in free fall, its speed increases by about 9.8 metres per second.
How can you define acceleration due to gravity?
In physics, gravitational acceleration is the acceleration of an object in free fall within a vacuum (and thus without experiencing drag ). This is the steady gain in speed caused exclusively by the force of gravitational attraction.
How does acceleration effect gravity?
Gravitational acceleration contributes to the total gravity acceleration, but other factors, such as the rotation of Earth, also contribute, and, therefore, affect the weight of the object. Gravity does not normally include the gravitational pull of the Moon and Sun, which are accounted for in terms of tidal effects.
What does acceleration due to gravity refer to?
Acceleration due to gravity is the acceleration that is gained by an object due to the gravitational force . Its SI unit is ms². It has a magnitude as well as direction.
