What effect of gravitational acceleration on Gravitational constant G?
The gravitational constant, G (big G), is a physical constant that doesn't change at all. The magnitude of gravitational acceleration, g (little g), has no effect on G.Little g is used as an approximation for near-surface gravity of a planet (or other large mass). The reason it is used is because the formula for universal gravity and Newton's second law:F = G (mplanet*mobject)/(r3) -- r is the distance between the centers of massF = mobject*aobjectyields (when set equal and dividing out the mass of the object): aobject = G (mplanet)/r3As you can see, the acceleration due to gravity won't change much for distances near the planet's surface. We call the above magnitude, g. Each planet has its own g and Earth's is about 9.8 m/s2.
For a car moving around a circular track at a constant speed the acceleration is?
constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.
Why is the mass of an object same on the moon as it is on earth but the weight is different?
Mass is the amount of matter in an object. It does not change based on gravity. Weight is the force an object exerts 'downward' due to gravitational acceleration. Force = (mass)*(acceleration). Acceleration due to gravity is less on the Moon than on Earth.
How are constant speed and constant acceleration different?
There is a huge difference between constant speed and constant acceleration. Constant speed is when the object is travelling constant, no change in its velocity and acceleration or in other words no extra force to speed up. Constant acceleration when the object is acceleration constant, it means that the speed of the object is change at the same rate each second. The acceleration rate at which the object is travelling is constant. for example, when a car is stationary at a traffic light and it starts acceleration, picking up speed but the rate of acceleration will not constant because the amount of force applied differs each second due to the acceleration rate.
What is the formula used to calculate the weight of an object if you are given the mass in kilograms?
Mass is a property of matter and is therefore a constant. Weight however can change, it is the force exerted by that mass in a gravity field. Thus in different gravity fields a constant mass will weigh differently. Weight = Mass * the acceleration of gravity.
How does Acceleration relate to gravity?
Acceleration is the rate of change of velocity over time. In the context of gravity, objects near the Earth's surface experience a gravitational acceleration towards the center of the Earth of approximately 9.81 m/s^2. This gravitational acceleration causes objects to fall towards the Earth at an increasing rate due to the force of gravity acting upon them.
Why acceleration due to gravity becomes constant?
Acceleration due to gravity becomes constant when an object is in free fall because there is no external force acting on it to change its velocity. This leads to a constant acceleration towards the center of the Earth, known as the acceleration due to gravity (9.81 m/s^2).
Are there any variables that can change acceleration due to gravity?
In a word, no. At least not that we know of. We're still stuck at the bottom of this gravity well, and we have only limited tools that we can use to get out. None of those tools alter the gravitational constant one bit.
What is the difference between uniform acceleration and constant acceleration?
Uniform acceleration refers to a situation where an object's velocity changes by the same amount in each unit of time. Constant acceleration, on the other hand, means that the object's acceleration remains the same throughout its motion. Uniform acceleration leads to a constant increase in velocity, while constant acceleration implies that the rate of change of velocity remains consistent.
What effect of gravitational acceleration on Gravitational constant G?
The gravitational constant, G (big G), is a physical constant that doesn't change at all. The magnitude of gravitational acceleration, g (little g), has no effect on G.Little g is used as an approximation for near-surface gravity of a planet (or other large mass). The reason it is used is because the formula for universal gravity and Newton's second law:F = G (mplanet*mobject)/(r3) -- r is the distance between the centers of massF = mobject*aobjectyields (when set equal and dividing out the mass of the object): aobject = G (mplanet)/r3As you can see, the acceleration due to gravity won't change much for distances near the planet's surface. We call the above magnitude, g. Each planet has its own g and Earth's is about 9.8 m/s2.
Why is the ball deccelerating on an inclined plane?
The acceleration due to gravity remains constant, regardless of incline. The fact that it is on an incline does not change the fact that it will remain constant, it will only change the component of that acceleration being applied to the ball.
What variables affect gravity?
It helps to look at the formula for gravitational attraction. The force of gravity between two objects depends on:* The gravitational constant (which doesn't change) * The mass of the one object * The mass of the other object * The distance between them
Is there an acceleration when an object traveling at constant velocity and why?
No, there is no acceleration when an object is traveling at a constant velocity. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change and therefore no acceleration.
When the velocity of a particle is constant its acceleration is also constant?
When the velocity of a particle is constant, it means there is no change in speed or direction. Therefore, its acceleration is zero because acceleration is the rate of change of velocity. If the velocity is constant, there is no change to be measured, so the acceleration is constant at zero.
If an object is moving at a constant velocity what do you know about its acceleration?
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
Does mass change when gravity changes?
No, an object's mass remains constant regardless of changes in gravity. Mass is an intrinsic property of an object and is not affected by the gravitational force acting on it. However, an object's weight, which is the force exerted by gravity on the object, will change with variations in gravitational pull.
What is gravitational accelleration?
Gravitational acceleration is the acceleration experienced by an object due to the force of gravity. On the surface of the Earth, the average gravitational acceleration is approximately 9.81 m/s^2, meaning objects will accelerate at this rate towards the Earth when in free fall.
