· 6y. Derive means to obtain the result from specified or given sources. For example, you might have other formulas that have those variables in it, and you’re supposed to use those formulas, and manipulate them algebraically, to get the final result in your link.

Building on what you have learned so far and what Galileo presented, we have what my physics teacher, Glenn Glazier, liked to call the Five Sacred Equations of Kinematics for constant acceleration. In these equations, v is velocity, x is position, t is time, and a is acceleration. Remember, Δ means change in.

There are four kinematic equations when the initial starting position is the origin, and the acceleration is constant:

• v=v0+at. v = v 0 + at.
• d=12(v0+v)t d = 1 2 ( v 0 + v ) t or alternatively vaverage=dt. v average = d t.
• d=v0t+(at22)
• v2=v20+2ad.

Explanation: Constant Acceleration: They can use the time it takes for the ball to roll between the marks and from that calculate the acceleration at various different points on the ramp, which should all yield the same result (meaning the acceleration does not change with respect to time).

So when you roll a ball down a ramp, it has the most potential energy when it is at the top, and this potential energy is converted to both translational and rotational kinetic energy as it rolls down.

In a Ferris wheel, forces are not balanced. Objects that have circular motion have something called “centripetal force”. Centripetal is a word meaning “centre seeking.” The centripetal force always points to the centre of the circle. Ferris wheel physics is directly related to centripetal acceleration.

a ferris wheel rotates counter-clockwise has a radius of 20m and rotates 2.5rev/min. the bottom of the wheel is 12m above the ground. Assume you get on the bottom.

As you near the bottom, your body is in motion downwards, but now the ground is pushing back to slow that motion; in other words, the normal force increases, resulting in a heavy feeling.

This is because as the Ferris wheel spins the seats, or gondolas, can freely rotate at the support where they are connected to the wheel. The Ferris wheel spins upwards with the help of gears and motors, while gravity pulls the wheel back down again. This cycle continues for the duration of the ride.

SkyWheel Helsinki, formerly known as Finnair SkyWheel, is the only Ferris wheel in the world that have a sauna in one of its gondola cabins….World’s tallest Ferris wheels.

Observe that the normal force is greater at the bottom of the loop than it is at the top of the loop. When at the top of the loop, the gravitational force is directed inwards (down) and so there is less of a need for a normal force in order to meet the net centripetal force requirement.

Here, the centripetal force is the difference between the force of the track pushing up and gravity pulling down. Near the top of the loop, however, gravity and the track both act with a downward force and work together to provide the centripetal force; their forces add together.

At the top of the loop, when you’re completely upside down, gravity is pulling you out of your seat, toward the ground, but the stronger acceleration force is pushing you into your seat, toward the sky. Since the two forces pushing you in opposite directions are nearly equal, your body feels very light.

133 km/h is easy to reach and, ok, you have wind and friction but you can also keep on pushing the accelerator to counter that. Let’s say, realistically, a car going at 150 km/h with the accelerator locked with a brick should be able to make the entire Loop with relative ease.

When you go around a turn, you feel pushed against the outside of the car. This force is centripetal force and helps keep you in your seat. In the loop-the-loop upside down design, it’s inertia that keeps you in your seat. Inertia is the force that presses your body to the outside of the loop as the train spins around.

When you go upside down on a roller coaster, inertia keeps you from falling out. This resistance to a change in motion is stronger than gravity. It is what presses your body to the outside of the loop as the train spins around.

Roller coasters are a prime example of this dynamic. The fears of safety bars failing, cars flying off of the track, or support beams collapsing may pop up even as riders strap in and grin with anticipation. Fortunately, roller-coaster accidents are relatively rare.

There are primarily two types of roller coasters: steel and wooden.
