Acceleration due to gravity coursework

The velocity time graph is in a straight line, meaning it was going at a constant acceleration. It was heading in a positive direction refer to graph 1.

The Earth is not spherically symmetric, but is slightly flatter at the poles while bulging at the Equator: There are consequently slight deviations in both the magnitude and direction of gravity across its surface.

The net force or corresponding net acceleration as measured by a scale and plumb bob is called "effective gravity" or "apparent gravity". Effective gravity includes other factors that affect the net force.

Legal definition[ edit ] In the third General Conference on Weights and Measures defined a standard gravitational acceleration for the surface of the Earth: The surface of the Earth is rotating, so it is not an inertial frame of reference.

Because the force due to gravitational attraction between two bodies the Earth and the object being weighed varies inversely with the square of the distance between them, an object at the Equator experiences a weaker gravitational pull than an object at the poles. In combination, the equatorial bulge and the effects of the surface centrifugal force due to rotation mean that sea-level effective gravity increases from about 9.

Anywhere on Earth away from the Equator or poles, effective gravity points not exactly toward the centre of the Earth, but rather perpendicular to the surface of the geoidwhich, due to the flattened shape of the Earth, is somewhat toward the opposite pole.

About half of the deflection is due to centrifugal force, and half because the extra mass around the Equator causes a change in the direction of the true gravitational force relative to what it would be on a spherical Earth.

Weightlessness actually occurs because orbiting objects are in free-fall.The gravitational potential energy equals the mass times gravity times the vertical height above the ground.

When an object falls, its grav PE decreases and its kinetic energy increases. Mass is considered a measure of an object’s inertia, and its weight is the force exerted on the object in a gravitational field. On the surface of the Earth, the two forces are related by the acceleration due to gravity: F g = mg.

Kilograms and slugs are units of mass; newtons and pounds are units of weight.

Heh, I’d forgotten Bambina! So many people to keep track of in Worm. ^^; Honestly if we’re looking for the biggest “challenge” it would probably be something like Accelerator from ACMI- but then again, someone like that is an enormous challenge to EVERYBODY, so that doesn’t mean much.

Acceleration Due to Gravity Formula Questions: 1) The radius of the moon is x 10 6 m. The mass of the moon is x 10 22 kg. Find the acceleration due to gravity on the surface of the moon.

Answer: On the surface of the moon, the distance to the center of mass is the same as the radius: r = 1.
