Kinematics

If the opposing forces are pulling exactly opposite of each other, then take the difference of the magnitudes of the two forces (subtract the smaller value from the larger value), and the direction vector of the resultant force is in the same direction as the larger force.

The kinetic energy of a moving object depends on its mass and its velocity. The formula for kinetic energy is 0.5 x mass x velocity^2. This means that both increasing the mass or the velocity of the object will increase its kinetic energy.

It is probably around 105mph the spedometer on the 250 reads a little high once you get going that fast, once I was going downhill into the wind and it read 115, i was probably going 110. I was tucked behind the windsheild, and Im not a big guy.

The distance a book is from the floor can be calculated using the formula for gravitational potential energy: PE = mgh, where PE is potential energy, m is mass, g is acceleration due to gravity, and h is height. Given that the potential energy (PE) is 98 J, mass (m) is 10 kg, and acceleration due to gravity (g) is 9.8 m/s^2, you can solve for h to find the height the book is from the floor.

On a distance vs time graph, terminal velocity appears as a flat line after the initial acceleration phase. This flat line indicates that the object is moving at a constant speed and has reached equilibrium between the gravitational force pulling it downward and the air resistance pushing back up, resulting in no further change in speed.

170 km per hour equates to 105.6 mph.

The average speed is 332.31 miles per hour.

Yes, in a hydraulic system, when a larger piston is pushing on two smaller pistons, the force applied to the smaller pistons will be the same as the force applied to the larger piston, assuming the system is closed and incompressible. This is due to Pascal's law, which states that pressure applied to a confined fluid is transmitted undiminished in every direction.

A Hamiltonian path in a graph is a path that visits every vertex exactly once. It does not need to visit every edge, only every vertex. If a Hamiltonian path exists in a graph, the graph is called a Hamiltonian graph.

The coefficient of static friction is the ratio of the force required to move an object to the force pressing the surfaces together when the object is not moving. The coefficient of kinetic friction is the ratio of the force of friction between two objects in motion to the force pressing them together. Both coefficients are dimensionless values specific to the two surfaces in contact.

Kinetic energy is the energy an object possesses due to its motion, while potential energy is the energy that an object has due to its position or state. Kinetic energy is dependent on an object's velocity, while potential energy is dependent on its height, position, or configuration.

There are many kinds of potential energy but only one kind of kinetic energy.

Using gravitational energy as potential energy we get.

mgh=1/2mv2

simplifying gives

2gh=v2

it is a value unique for every spring and depends on the materials. it doesn't change if the characteristics of your spring don't. if we have a spring with k spring constant and cut it in 2, the resulting springs still have k spring constant.

the spring force depends on the spring constant. this formula F=k*x gives the force applied to a body by a spring, when it hase been pulled by x from it's natural state.

In order to translate feet and seconds into feet per second, all you have to do is divide the number of feet by the number of seconds. In this case, the answer is 7.634 ft/s

432 km/h = 268.4 mph

To double its kinetic energy, the object's speed should be increased to approximately 14.1 m/s. This is because kinetic energy is directly proportional to the square of the object's speed (KE = 1/2 * m * v^2). Doubling the speed quadruples the kinetic energy.

YES. Infact, an object can have infinitely different moment of inertias. It all depends on the axis about which it it rotating.

You can allow an object to rotate about any axis (this may or may not pass through the object).

The Space Needle's elevator travels at a speed of 10 miles per hour, taking visitors to the observation deck in around 41 seconds.

If s = displacement, u = initial velocity, a = acceleration, t = time.

Then s = ut + 1/2at2 Be careful to keep units consistent

Faster particles have more energy than slower particles, yes.

all i know is it gets from 0-60 in 4.1 secs

For a simple answer, we have to ignore air resistance.

As the skydiver's downward momentum increases, the earth's upward momentum

increases by an identical amount. The total momentum of the earth-skydiver system

remains constant.

When two objects have the same velocity on a position graph, their position vs. time graphs will have parallel lines with the same slope. This indicates that both objects are covering the same distance in the same amount of time, resulting in the same velocity.
