How much force is required to accelerate a 10kg bicycle along with it's 10kg?
To accelerate a 20kg bicycle (10kg bike + 10kg rider) at a rate of 2 m/s^2, you would need a force of 40 newtons. This is calculated by multiplying the mass (20kg) by the acceleration (2 m/s^2).
What is the kinetic energy of a 10kg dog chasing a car a 5 ms?
The formula for kinetic energy is (1/2) x mass x velocity2. If mass is in kg. and speed in meters per second, the energy will come out in Joule.D. 125 J
An example of kinetic energy formula?
K= 1/2mv2 eg. 10kg, 30mph convert speed into meter/second 30mph = 13.4112m/s so, half of mass = 5 multiplied by the velocity squared 0.5 x 10 x (13.41122) =899.3014272 joule
Which would have greater effect on kinetic energy of an object - doubling the mass or doubling the velocity?
Doubling mass affects kinetic energy in that the greater the mass, the greater the kinetic energy. OK, but if you have a 10kg mass traveling at 2m/s and it bumps into and sticks to a 10g mass, the resultant speed would be 1m/s. The momentum stays the same. KE before is 10*2*2/2= 20, while the KE after is 20*1*1/2= 10. So it is not that the above answer is wrong, but rather, you question is not clear.
What is the effect of an object's height on its potential energy?
The potential energy you mentioned is known as gravitational potential energy, which involves gravity. Gravity is a wonderful mechanism which acts like a rubberband. Let say the object is you riding a bicycle. To climb a hill, you need to input your kinetic energy which is to pedal hardly to increase your altitude(height). When you are at the top of the hill(summit), you have the greatest gravitational potential energy. What is the difference between you at the bottom of the hill and you at the top of the hill? The you at the summit has stored more energy in your mass, which can be converted only into kinetic energy when you roll down the hill.
How do find kinectic energy?
Ke=½MV² Kinetic Energy equals one half the mass of the object multiplied by the square of the velocity. If the object weighs 10kg moving at 5 meters per second... ½10 = 5 5² = 25 5 x 25 = 125 has a kinetic energy of 125 Joules

How much work must be done on a 10kg bicycle to increase its speed from 2 M's to 3 M's?
Work done = increase in kinetic energy ie 1/2 * 10 * (3+2)(3-2) [recall a2 - b2 = (a+b)(a-b)] Hence work done = 25 joule.

Which produces the most energy 10kg of what?
Fusing 10 kg of hydrogen -apex
How can you find the kinetic energy without velocity in the question?
To find kinetic energy without velocity, you can use the formula for kinetic energy, which is KE = 0.5 * m * v^2, where m is the mass of the object and v is the velocity. If velocity is not given, you will need additional information, such as the height from which an object falls (in the case of gravitational potential energy) or the force applied over a distance (in the case of work-energy theorem), to calculate kinetic energy without velocity.

Which weighs more 10kg stack of books or 10kg piece of Styrofoam?
Both the 10kg stack of books and the 10kg piece of Styrofoam weigh the same amount, 10kg, because weight is a measure of the force due to gravity acting on an object's mass.
What is 10kg called'?
10kg is called ten kilograms.
Explain the energy conversions that occur as a pendulum swings and how does this demonstrate conservation of energy?
As a pendulum swings, energy is converted between potential energy (at its highest points) and kinetic energy (at its lowest points). At the highest point, the pendulum possesses maximum potential energy due to its height above the ground. As it swings down, this potential energy is converted into kinetic energy, reaching its maximum speed at the lowest point. The energy conversions during the swinging of a pendulum demonstrate the principle of conservation of energy, where the total mechanical energy (the sum of potential and kinetic energy) remains constant throughout the motion, disregarding any energy losses due to friction.
