How can you calculate the energy in a rolling billiard ball?
KE = kinetic energy in Joules
Add the linear KE to the rotating KE
Say velocity (v) = 2 m/s
mass (m) = 0.17 kg
radius (r) = 0.0286 metres
Mass moment of inetia (MMI) = 0.4 * m * r2 = 0.00005562128 kg-m2
Rotation rate = v / r = 69.93 radians / second
Linear KE = 0.5 * m * v2 = 0.340 Joules
Rotating KE = 0.5 * MMI * ( rad / sec 2 ) = 0.136 Joules
Total KE = 0.476 Joules
If you are driving 70 mph what is the maxiumum kph speed?
If you are driving 70 mph, the maximum speed in kilometers per hour (kph) would be 112.65 kph. This is because 1 mile per hour is equal to 1.60934 kilometers per hour.
What does not have the same units as the others Kinetic Energy Momentum Potential Energy or Work?
Momentum does not have the same units as the others. Kinetic energy is measured in joules, potential energy in joules, work in joules, but momentum is measured in kilogram meters per second (kg m/s).
What is the formula of energy transmission?
Energy can take different forms, and it can be transmitted in different ways. Therefore, there is not a single formula, but several, depending on the type of energy transmission. In general, the total amount of energy that arrives at the destination will be less than or equal to the amount of energy that leaves the origin.
Why do you use RPMS instead of meters per second?
Here in the United States we use the Standard System not the Metric System like the rest of the world uses.
Why does a golf ball make a bigger dent in the sand when dropped above the sand at higher heights?
It has more momentum from a higher height. Because momentum is always conserved, and momentum is the product of mass times velocity, more sand particles must move away faster in order to conserve the momentum of a heavy ball moving fast. The ball is moving faster from a higher height because the acceleration due to gravity (-9.81 m/s^2) increases the velocity of a falling object after each second its been falling.
Place the object on the plane. Slowly increase the angle of the plane until the object begins to move at angle Θ. The µs = tan Θ.
For µk, same process, but give the object a little push at each increasing value of Θ.
because water has higher viscosity than air so resisting the movement of the body in it more than air so decreasing the velocity
How many seconds to travel 60 feet at 100 mph?
At 100 mph, an object is traveling about 146.67 feet every second. Therefore, to travel 60 feet at 100 mph would require about 0.41 seconds.
Is a tractor pulling plow kinetic energy or potential energy?
The tractor pulling the plow is an example of kinetic energy because it is in motion and doing work by moving the plow through the soil. Potential energy is associated with stored energy due to an object's position or condition, such as the plow being lifted up and not yet in motion.
It would take approximately 7.6 hours to drive from San Francisco to Los Angeles at a constant rate of 55 miles per hour.
What is the correct angle of throwing a javelin?
The correct angle of throwing a javelin is 45 degree.The physics concept behind this is known as impulse.According to this law if an object is thrown at an angle of 45 degree it travels much range(horizontal distance) than throwing at any other angle this law not only applies for javelin but also for firing an cannon or shooting a gun on an arrow into the space.
What is the coefficient of restitution in elastic inelastic and plastic collision?
With a plastic impact, the coeffecient of restitution is 0.
With an elastic impact, the coeffecient of restitution is 0<e<1.
With an inelastic impact, the coeffecient of restitution is 1.
IS Thermal energy is kinetic energy or potential energy?
Thermal energy in a substance is kinetic energy
of the molecules that make up the substance.
Is kinetic energy increases as mass increases is that ture?
Kinetic energy for nonrelativistic speeds is 1/2 times mass times speed squared. If ONLY the mass increases, then the kinetic energy will also increase.
When you throw a basketball up in the air where does the gravitational pull of earth affect it most?
The gravitational pull of the earth is a tiny, tiny, tiny bit stronger at the lowest
point of the basketball's path, because it's closest to the center of the Earth.
But you would need ultra-high-precision instruments to detect the difference.
Would an airbag deploy on a rearend collision at 65 mph?
It should not, unless u hit an obstruction in front of you.
My father was rear ended on a 2003 camry at around 60mph, resulting in a totalled car(flew 150 feet with breaks applied) and the cars entire rear was jammed halfway inside the car.
No airbags deployed.
What is the velocity of a helicopter traveling 6 feet per second?
Its speed is 6 feet per second.
Its velocity is 6 feet per second in whatever direction it's going.
What is the speed of an object increases its kinetic energy .?
The kinetic energy depends on both mass and speed. If either mass or speed increase, the kinetic energy will increase as well.
