Gravity

I would help you if i could, but i am also stuck on that level! :/ If you beat it already, you should help me. :D

It depends on how you push it down.

Terminal velocity (top speed) is when the driving force is matched by the two opposing drag forces, air drag force and rolling resistance force.

The (constant) driving force (due to gravity) you get from :

force (N) = mass (m) of bike and rider in kg * g * sine ( incline angle in degrees) )

( g = local gravity rate (use 9.8 (m/s)/s ) )

The air drag force in newtons = drag coefficient (use 0.24) * velocity ^2

(velocity is in m/s)

The (constant) rolling resistance force in newtons = m * g * cosine (incline angle ) * rolling resistance coefficient (use 0.03).

Sequence : guess at top speed (in m/s), calculate the for and against forces for that speed, and adjust this guess until its zero.

displacement (s)=initial velosity(u)*time(t) + 1/2 acceleration (a)*(t^2) from a stationary start this simplifies to s=1/2a(t^2) this arises from the fact that a is the second integral of s with respect to time eg. d/dt=s: x=st+u (velosity v=distance*time +initial velosity) (d^2)/d(t^2)= s(t^2)/2+ut+d=a as we are measuring displacement and not position, the constant of integration d drops, leaving a=s(t^2)/2+ut : s=ut+1/2a(t^2)

example: if u put a small object on a roller coaster ride, it falls out in a straight line...

example: if u go on the empire state building and drop a object in would drop to the ground in a straight line all the way down.

Gravity

Nothing.

Actually gravity is pushing you down but there is enough air resistance on the earth to stop us feeling heavy and crushed

Theoretically it's independent,

but often in practice you just weigh something and convert.

February, 1851. More details are available from the wikipedia article about the Foucault pendulum.

Since on average, you would weigh about 40% on Mercury as you would weigh on Earth, with practice you could expect to be able to jump about 2½ times as high.

That is a myth based on the supposed effect of the coriolis force. The rotation of the earth is supposed to impart clockwise motion in fluids in the Southern hemisphere. While this works for atmospheric systems (storms), whirlpools are too small to be so affected: initial and local conditions have much more of an effect.

Its pull on the earth would be 25% as strong.

Downward motion is defined as the movement of one's center of gravity towards the performance surface.

To ascend a slope, you have to overcome the force of gravity that is pulling down on you. Coming down a slope, gravity will tend to accelerate your descent (as it would when sliding down a hill). Although you still have to lift your feet from the ground (opposing gravity) if you are walking, you do not have to lift your body through the entire step, as you do when going uphill.

Gravitational attraction is proportional to mass.

It depends on strength of the rum or more specifically the percentage of alcohol by volume. Most commonly the ABV is 40% (80% proof) and the density is 0.9755 meaning its around 2.5% less dense than water.

The episode is called 'Wheels'. I believe it is episode number nine (9). Its about 29:30 into the episode.

Mainly because the two are utterly unrelated.

The acceleration of gravity on the surface of Mars is 3.711 meters per second-squared,
compared to 9.807 on the Earth's surface.

So you would weigh (75 pounds) x (3.711/9.807) = 28.38 pounds (rounded)

The sun's gravity keeps the Earth in orbit around it, causing it to move in an elliptical path. This gravitational force also influences the tides on Earth by pulling on the oceans, creating the phenomenon of high and low tides. Additionally, the sun's gravity affects the Earth's axial tilt and rotation.

All objects, under these conditions, will accelerate at the same rate as they fall.

(Note: Just the fact that you can call it a "falling" object is one of the effects of gravity.)

If the ball were simply dropped, the person dropping the ball and a stationary observer should see the same thing.

You can do the following. Make a diagram to illustrate the initial velocity at a certain position, and the velocity after a short time, delta-t. Calculate the change of velocity (delta-v) during that time. Divide delta-v by delta-x to get the acceleration. Finally, calculate the limit as delta-t tends toward zero - that is, figure out what happens when delta-t gets smaller and smaller.

Gravity does not depend on density. Gravity is the gravitational pull that is invisible and cannot be touched or changed. Density is how much matter is packed within an object, which can be changed. Gravity and density are two totally different things, and are in no way related, therefore gravity does not depend on density.
