How far an object has moved (speed x time)?
To measure smaller object use ruler or measuring tape.
Or
For long paths use laser distance measurer
Or
For further long distances use Side road millage stones
Or
For Still long distances JUST USE google earth :p
Hope it helped
Energy balls are not a real physical phenomenon in the scientific sense. The term "energy balls" is often used in a metaphorical or pseudoscientific context to refer to certain spiritual or metaphysical practices.
An object with mass 'm' moving with velocity 'V' has kinetic energy of [ 1/2 m V2 ] .
In order to bring it to rest, its velocity has to be reduced to zero, and in order to
accomplish that, the kinetic energy has to be drained off and sent somewhere else.
An external force has to absorb energy from the object, i.e. do negative work on it,
equal to its kinetic energy, or
- 1/2 m V2
Her final speed is 14.5 m/s.
The kinematics equation v = at + v0 will be useful here. Note that t is the time measured in seconds, a is the acceleration, v0 is the initial velocity, and v is the velocity after t seconds (the final velocity).
We are given that v0 = 10 m/s, a = 0.500 m/s2, and t = 9 s.
Using the above kinematics equation we get v = (0.500 m/s2)(9 s) + 10 m/s = 14.5 m/s.
Since speed = |velocity|, then her final speed = |14.5 m/s| = 14.5 m/s.
If this body is on earth, than the potential energy is the gravitational potential energy, U which equals mgy. M is the mass of the body, g is the acceleration of gravity, 9.8 ((m/s)/s), and y is the height. Thus, U = mgy. To solve for height, divide both sides by mg. y=U/mg
If a compact car and an SUV were both moving at 50 mph which would have the greater momentum?
Since momentum is mass x velocity, the vehicle with the greater mass would have more momentum in this case.
Kinetics of rectilinear translation?
The kinetics of rectilinear translation focus on the forces and accelerations acting on an object moving in a straight line. This can involve analyzing the forces causing the motion, such as friction or external forces, and determining the resulting acceleration and velocity of the object. In essence, it deals with the relationships between forces, mass, and motion in a straight line.
You haven't entirely defined the problem, however, if distance is fixed, than velocity and time vary in an inverse relation to each other. How long does it take to travel one mile? The faster you travel, the less time it takes. So the relationship is inverse. More of one means less of the other. But only for a fixed distance. You could just as well imagine that you will travel for a fixed period of time. Then there is a direct relationship between speed and distance traveled. The faster you travel, the farther you will go.
Normal acceleration is about 10 meters per second squared, so there is a force backward capable by itself of producing an acceleration of 3 meters per second square. Now use the formula. Now use the formula F=ma.
Mach 3.5 is equivalent to approximately 2,685 miles per hour (mph).
As the car moves down the roller coaster track, the potential energy of the car decreases and is converted into kinetic energy. The total mechanical energy of the system (car + passenger) is conserved, so at any point along the track, the sum of the potential and kinetic energies remains constant. Using the conservation of energy principle, we can analyze the motion of the car and passenger along the roller coaster track.
Is the graph created by Pressure vs Volume an exponential graph when constant in temperature?
No, when pressure and volume are inversely proportional at constant temperature, the graph of pressure vs. volume is a straight line. This relationship is described by Boyle's Law, which states that pressure multiplied by volume is constant when temperature is held constant.
What are five ways kinetic energy can be dispersed?
Through energy conversions
-KE-Thermal energy
-KE-Potential E
-KE-Chemical E
-KE-Light E
Through friction
What is it called when a scalar and a vector are multiplied together?
When a scalar quantity(if it has positive magnitude) is multiplies by a vector quantity the product is another vector quantity with the magnitude as the product of two vectors and the direction and dimensions same as the multiplied vector quantity
e.g. MOMENTUM
To increase the kinetic energy of the small ball of clay when throwing at a person, you can either increase the velocity at which you throw the ball or increase the mass of the clay ball. This can be achieved by exerting more force when throwing the ball or using a larger amount of clay to increase its mass, resulting in higher kinetic energy upon impact.
Cars can go up to 500mph...Not about this question though but a horse can go 60mph that's fast!
At what point PE at a maximum?
The potential energy of an object is at a maximum when it is at its highest point in a gravitational field, such as when it is lifted to its maximum height or at the peak of a motion like a swing. At this point, all of its energy is in the form of potential energy due to its position relative to the Earth's surface.
When the average kinetic energy of a substance's particles increases, the substance's temperature also increases because temperature is a measure of the average kinetic energy of the particles. Conversely, when the average kinetic energy of a substance's particles decreases, the substance's temperature decreases because there is less molecular movement and lower energy levels overall.
A measure of the quantity of atomic kinetic energy contained in an object?
The measure of the quantity of atomic kinetic energy contained in an object is called temperature. Temperature is a metric that defines the average kinetic energy of the particles within a substance. It provides an indication of how hot or cold an object is based on the movement of its atoms or molecules.

What is the uncertainty in measurement when using a stopwatch to measure time?
The uncertainty in measurement when using a stopwatch typically depends on the stopwatch's resolution and the human reaction time involved in starting and stopping the watch. It is generally recommended to estimate the uncertainty to be half of the smallest division on the stopwatch. To reduce uncertainty, multiple measurements should be taken and averaged.
To find the acceleration of an object moving in a straight line, you must calculate the change in velocity during a unit of time. Acceleration is the rate of change of velocity over time, not distance. It is given by the formula acceleration = (final velocity - initial velocity) / time.
For this and similar questions, use the formula PE = mgh (potential energy = mass x gravity x height). If mass is in kilograms, gravity is 9.8 meters/sec2, and height is in meters, then the energy is in Joule.
