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.
Energy = Force x Distance, therefore in this case it is 134.7G x 7.19, since the force attracting a mass M to the earth is MG. Now G = 9.81 meters/sec2, so the sum comes to 134.7 x 9.81 x 7.19, and the answer is in Joules. Value of answer = 9500.9 Joules.
That's some heavy man by the way, he should diet!
find a materials with a high coefficient of static friction and use them against each other ( like rubber dry concrete ) and bound them to the object and the surface it rests on. Increase the normal force by adding mass on the object or applying a perpendicular force to the surface of the object.

Where on a roller coaster does energy transform?
As it starts to climb the lift hill, the electrical energy builds potential energy. On its way down the first drop, the cars gain kinetic energy (energy of motion) and lose potential energy (stored energy). When it goes up the next hill, the potential energy increases and kinetic decreases, evident in the cars slowing down. Potential is greatest at the top of the highest hill. Along the way, more energy is lost in friction and sound energy.
In addition to the mass of both objects and the distance the stationary object was moved, you need to know the coefficient of restitution or the type of collision (elastic or inelastic). This information will help you determine how much kinetic energy was transferred during the collision and allow you to calculate the velocity of the moving object before and after the collision.
Angle between force and displacement to get minimum work?
The work done by a force is the dot product of the force and the displacement of the point of application of the force i.e.
component of force in the direction of displacement * displacement
or
component of displacement in the direction of force * force
let W be the work done. Then :
W = F.S
W = |F|*|S|*cos(θ) ---- equation 1
where F and S are force and displacement in vector form and |F|, |S| are their magnitudes respectively. cos(θ) is the angle between line of action of force vector and displacement vector.
It is clear from the equation 1 that work will be minimum when cos(θ) is minimum. It is known from trigonometry that minimum value of cos(θ) is -1 which is for angle 1800 or π radians. So work done will be minimum when angle between force and displacement vector is π radians or 1800 i.e. when point of application of force is displaced exactly opposite to the direction of application of force.
I appreciate the last attempt to answer the question, but I think it is wrong. The answer should be 90°, because although cos180° = -1, the negative sign in
- FScos180° only signifies that the work done has taken away energy from the system, or it signifies that the work is done in the opposite direction, implying that work is done. When the angle is 90°, on the other hand, work done = 0, ie, no work is done at all. Thus the answer should be 90°.
(The above answers define minimum work differently.
The first answers is if minimum work is negative work, therefore if you do work in the opposite direction of the displacement, the work you do is negative and is less than 0. Minimum work here is the work that is the lowest number.
The second answer defines minimum work as the magnitudeof the work done being minimized. Since magnitude is always positive, minimum work in this case would always be zero. Which one is correct depends on the situation you are dealing with.)
