Is gravitational forces and acceleration equivalent?
When you notice that the unit of "gravitational field strength" ... (force) per (unit mass) ...is exactly the unit of acceleration, you realize that the question is quite trivial. It's aboutas deep, in a way, as asking "How does 4 compare with 2 + 2 ?"Force . . . . . . . . . . . . 1 newton = 1 kilogram-meter / second2Force / unit mass . . . 1 newton / kilogram = 1 meter / second2 (acceleration)SI:Gravitational field . . . . . 9.8 newtons per kilogram ( = 9.8 meters per second2 )Freefall acceleration . . . 9.8 meters per second2English:Gravitational field . . . . . 1 poundforce per poundmassFreefall acceleration . . . 32.2 feet per second2
How does your weight mass and the normal force exerted by the floor change when you are in an elevator that starts from rest and accelerates upward?
When you are in an elevator that starts from rest and accelerates upward, your weight (mass times gravitational acceleration) remains constant because your mass does not change. However, the normal force exerted by the floor increases during the upward acceleration. This is because the elevator's acceleration adds to the gravitational force, resulting in a greater normal force acting on you, which can be felt as an increase in apparent weight.
How does the temperature change as current move towards the equator?
As you move towards the equator, generally, temperatures increase due to the more direct angle of sunlight hitting the surface. This results in warmer climates near the equator compared to regions further from it.
How does earths surface temperature change as you move from the equator towards the poles?
As you move from the equator towards the poles, Earth's surface temperature generally decreases. This is primarily due to the curvature of the Earth, which causes sunlight to be more concentrated at the equator and more dispersed at higher latitudes. Additionally, the angle of sunlight strikes the surface at different latitudes, leading to variations in heating. Consequently, regions closer to the poles experience colder temperatures compared to those near the equator.
What is the rate change in velocity?
The rate of change in velocity is known as acceleration.
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 does the weight of an object change when it is moved from the equator to the poles?
The weight of an object changes when it is moved from the equator to the poles due to the variation in gravitational force caused by the Earth's rotation. The force of gravity is slightly stronger at the poles compared to the equator, leading to a small change in weight.
What is the relationship between static acceleration and an object's position in a gravitational field?
The relationship between static acceleration and an object's position in a gravitational field is that the static acceleration of an object in a gravitational field is constant and does not change with the object's position. This means that the object will experience the same acceleration due to gravity regardless of where it is located within the gravitational field.
Why would acceleration be affected by angle of inclination?
Acceleration is affected by the angle of inclination due to the component of gravitational force acting parallel to the surface. As the angle increases, a larger portion of the gravitational force contributes to accelerating an object down the slope. Conversely, at smaller angles, less gravitational force acts parallel to the incline, resulting in lower acceleration. Thus, the steeper the incline, the greater the acceleration experienced by an object moving down it.
What is gravitational accelleration?
gravitational acceleration is the acceleration due to the force of gravity (your weight). Newton's second law is F = ma, as this can be rewritten for Weight (the gravitational force) as W = mg where g is the gravitational acceleration. On Earth g = 9.81 m/s/s. If you traveled to a different planet it would change as the force of gravity would be different thus the gravitational acceleration would be different (on the moon it is 1.6 m/s/s on mars 4 m/s/s on Jupiter 25 m/s/s)
How will your weigth change if you go higher above the earth?
When you go higher, the gravitational acceleration drops ( <9,8m s-2 ) So that means that you weigh les than on the surface of the Earth, but your MASS stays the same!
Why gravitational constant is constant while when acceleration due to gravity is change?
gravity of earth is constant in any plane but the acceleration may vary becoz of irregular plane
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.
How much does a 70 kg man weigh on the moon?
From Wikipedia, the gravitational acceleration on the Moon (on its equator) is 1.622 m/s2. This is the same as 1.622 N/kg, so you can multiply the mass by this number to get the weight in Newton. (The man's mass, of course, will still be 70 kg on the Moon. His weight will change, but his mass will not change.)
What is 19.8 meters per second squared?
It is a specific measure of a rate of change of velocity, also known as acceleration. As a rough approximation it is about equal to twice the gravitational acceleration on Earth.
What will an object weigh on the Moon's surface if it weighs 100Newtons on Earth's surface?
We know that the weight of any object = the mass of the object* g, [where g is the gravitational acceleration]. For any object the mass will be constant in any case. Though Einstein proved that if any object moves with the velocity greater than light it's mass will increase. But in this case the mass will not change. But the gravitational acceleration will change. It is proved that the gravitational acceleration of moon is 1/6 of the gravitational acceleration of the earth. So, the weight of the object on moon will be 100/6 newton=16.666(apporximately) newtons.
As the speed of a bicycle moving along a horizontal surface increases from 2 meters per second to 4 meters per second the bicycle's gravitational potential energy?
There is no change. The bike is moving along a horizontal surface, and only a change in height can change the gravitational PE.
