Kinematics

One characteristic of projectile motion is that the object follows a curved path under the influence of gravity. This motion can be divided into horizontal and vertical components that are independent of each other. The object’s velocity changes due to the constant acceleration from gravity.

The average kinetic energy of particles in an object is directly related to the temperature of the object. As temperature increases, the average kinetic energy of the particles also increases. This is because temperature is a measure of the average kinetic energy of the particles in an object.

170 miles per hour is 273.59 kilometers per hour.

1 kilometre = 0.621371192 miles

280 kilometres = 173.98393376 miles

1mi = 1.609km

67km/h x 1mi/1.609km = 42mi/h

80 km/h = 49.71 mph

If the velocity is constant there is no acceleration. Speed is not velocity, velocity has speed and direction. I A car going around a circular track at 60 mph keeps the same speed but changes direction and thus accelerates at a constant speed.

Velocity is speed in a certain direction.

So change the speed but keep direction the same and you change the velocity.

or

Change the direction while keeping the speed the same and you change the velocity.

If the speed is constant, any change of direction is a change in velocity. Driving around in a circle is a case of constantly changing direction.

When you remove kinetic energy from a substance, its particles slow down. If enough kinetic energy is removed, the substance may transition from a gas to a liquid or a solid, depending on the substance.

90 miles/hour (5280 feet/1 mile)(1 hour/3600 seconds)

= 132 feet per second

================

If the ball's motion is in the horizontal direction, not far at all. So, let's assume you mean the ball's motion is entirely in the vertical direction, and the 50 joules represents the kinetic energy of the ball. If the 50 joules is all kinetic and the ball is heading upward, it will reach its highest point when its kinetic energy is zero and its potential energy due to gravity is at its greatest. At that point all the kinetic energy will have been turned into potential energy, so when the ball is at its apex, its potential energy will be 50 joules. The formula is pretty simple: Ep = mgh. In English, the potential energy, Ep, is the product of the mass, the acceleration due to gravity, and height. So, 50 = 2 * 9.8 * h. Solving for h gives you h = 2.55 meters.

You have a right triangle and can use trig. Degree mode.

tan(theta) = adjacent/opposite( y component )

tan( 60 degrees) = (5 m/s)/(y comp.)

y component = 5 m/s)/(tan 60 degrees)

= 2.887 m/s ( you can call it 3 m/s )

In chemistry, kinetic energy refers to the energy associated with the movement of particles. It is related to temperature, with higher temperatures leading to greater kinetic energy and faster particle movement. This energy is important in chemical reactions as it affects the rate at which reactions occur.

The kinetic energy increases as the velocity increases (KE = 1/2mv2) until terminal velocity is reached, at which point the velocity becomes constant, and kinetic energy will no longer increase. The potential energy and kinetic energy will be at equilibrium, where PE = -KE.

There is no finite answer to this, since the term Mach (the speed of sound through air or water) changes based on the temperature of the air itself. In 60 deg F air at sea level, Mach 1 is 761mph. In dry air at 68 deg F, mach 1 is 768 mph. Mach 1.4 is 1.4 x these speeds. Usually Mach speeds are used for objects travelling in air, but not always. Mach 1 in water is 4.3 times faster than air and Mach 1 in iron is 15 times faster than air.

A mass accelerates uniformly when a constant force is applied to it, resulting in a constant rate of change in velocity over time. This occurs in scenarios where there is no opposing force or acceleration due to factors such as friction, air resistance, or gravity.

You cannot directly calculate velocity using kinetic energy alone. Kinetic energy is defined as (1/2)mv^2, where m is mass and v is velocity. You can, however, use kinetic energy along with other information like mass or height to calculate velocity using principles of energy conservation.

To determine feet per second, divide the distance in feet by the time in seconds it takes to cover that distance. The formula for calculating speed is Speed = Distance / Time. For example, if an object travels 60 feet in 10 seconds, the speed would be 60 feet / 10 seconds = 6 feet per second.

You're looking at one specific velocity/time graph that we can't see.

From your description, we can tell that the object whose motion is described

by that graph is moving at a constant rate of speed ... which is exactly what

you just said while looking at the graph.

Kinetic energy is the energy of motion because it is associated with the motion of an object based on its velocity and mass. The faster an object is moving or the heavier it is, the more kinetic energy it possesses. This energy is converted into other forms during interactions like collisions.

47 kilometers per hour is 29.2 miles per hour.

Techniques like Qigong and Tai Chi are believed to channel and manipulate one's chi energy for various purposes, like promoting healing or improving wellness. However, physically moving someone using chi energy alone is not a documented or proven ability.
