The formula for kinetic energy is KE = 0.5 * m * v^2, where m is the mass and v is the velocity. Given that the kinetic energy is 1 J and the mass is 1 kg, we can rearrange the formula to solve for v. Solving for v, we get v ≈ 2 m/s.
The momentum of an object with a mass of 1 kg and a velocity of 10 m/s is 10 kg*m/s. Momentum is calculated by multiplying the mass of the object by its velocity.
KE=1/2MV^2 Or in other words, Kinetic Energy = 0.5 x Mass (1000g) x Velocity (measured in metres per second) Squared (make sure you only square the Velocity) For example if your 1kg ball was going at 2 metres per second, then the equation would look like this: KE = 0.5 x 1000 x 4 = 2000 Joules
The potential energy of an object at a particular height is given by the formula: Potential Energy = mass x gravity x height. At the top of its ascent, the ball's height is maximum, meaning all of its initial kinetic energy has been converted to potential energy. Therefore, the potential energy of the ball at the top of its ascent is 0.
The initial velocity needed can be calculated using the conservation of energy principle. The gravitational potential energy at height 20m is equal to the initial kinetic energy given to the mass. Using the equation for gravitational potential energy (mgh), where m = mass, g = acceleration due to gravity (9.81 m/s²), and h = height (20m), we can calculate the initial velocity. The total energy of the system will be the sum of the initial kinetic energy and the potential energy at height 20m.

The weight of an object on Earth is the same as its mass, which is 1kg in this case. Weight is a measure of the force of gravity acting on an object's mass.
The potential energy of an object at a particular height is given by the formula: Potential Energy = mass x gravity x height. At the top of its ascent, the ball's height is maximum, meaning all of its initial kinetic energy has been converted to potential energy. Therefore, the potential energy of the ball at the top of its ascent is 0.

1kg of lead at 400°C would have more energy because thermal energy is directly proportional to temperature, and the higher the temperature, the higher the thermal energy.

The energy produced when 1kg of a substance is fully converted into energy is given by Einstein's famous equation E=mc^2, where E is the energy produced, m is the mass of the substance (1kg in this case), and c is the speed of light. This equation shows that a large amount of energy can be generated from a small amount of mass.
The potential energy gained by a 1kg book elevated 4m can be calculated using the formula: potential energy = mass * gravity * height. Plugging in the values, we get potential energy = 1kg * 9.8 m/s^2 * 4m = 39.2 Joules.
