Lifting an object to a greater height requires more energy, but not any more force, than
lifting it to a not-as-great height.

Which type of energy is the person using to move the wheelchair up the ramp?
Mechanical force pushes the wheelchair up the ramp. The total weight multiplied by the height gain is the gain in potential energy. The energy needed is that plus a little extra to allow for friction. The potential energy in joules is the weight in Newtons times the height in metres.
How is work and energy different?
Work is the word used to describe anything that's being physically done whereas energy is what is needed for work to be done. So in a simple form - You need energy to work.
How much energy is needed in Joules for a 90 kg woman was to climb a ladder 6 meters in height?
The energy needed for a woman to climb a ladder is given by the change in potential energy she experiences. Defining the ground as being zero potential energy, her overall change in potential energy isEp = mghwhere Ep is the change potential energy, m is her mass, g is the gravitational acceleration (9.8m/s2 on earth) and h is the height she climbs.Ep = (90kg)(9.8m/s2)(6m) = 5292kg*m2/s2 or 5292 Joules
Why is energy needed by the body?
Energy is needed to keep your body in action!
What formula is used to find the amount of energy needed to lift a box?
Most of the energy related to lifting something up is related to gravitational potential energy, so you basically use the formula for gravitational potential energy: GPE = mgh (mass x gravity x height)
Which statement will be describe how enzymes effect chemical reactions?
Enzymes lower the activation energy needed to start a chemical reaction.
How do enzymes effect the energy profile?
It lowers the amount of activation energy needed
What it the term used to describe the energy needed to get a reaction started?
The energy needed to get a reaction started is called activation energy.
What effect does an enzyme have on a activation energy needed to start a reaction?
In chemistry it is called a catalyst. Enzymes decrease the activation energy needed to start a reaction.
What is the maximum amount of kinetic energy made from potential energy with 5kg mass?
The height in meters and the velocity in m/s are needed.
What term is used to describe the minimum energy needed by particles when they collide?
State the term used to describe the minimum amount of energy required for two colliding particles to rate
What is the term used to describe energy needed to get a rection started?
ACTIVATION ENERGY IS THE ENERGY WHICH IS REQUIRED FOR INITIALIZING OF ANY TYPE OF REACTION.
What term describe a substance that lowers the amount of energy needed to start a chemical reaction?
Catalyst
What is the minimum amounth of energy required for a reaction occur?
The minimum amount of energy needed for a reaction to take place is called the activation energy.
Describe the most complex problem you've recently been asked to solve What did you do What alternatives did you consider?
There are many ways in which a person could describe a complex problem that needed solving. A person may describe an energy crisis in scientific terms for example and propose an alternative energy source.
