How much force was applied to a box that requires 45 joules of work to push it up a 3 meter long ramp?
Work is done when energy is transferred
Lifting a box tranfers energy from the lifting device to the box giving it Gravitational Potential energy
The equation for GPE is mass (kg) x "gravity" (10m/s^2) x height (m)
The equation for Work is very similar!!
Work done = Force (N) x distance moved (m)
where Force (N) can be calculated from F=ma ------ Force = mass x acceleration!
Which put together gives us
Work Done = (mass (kg) x acceleration (m/s^2)) x distance moved (m)
In your example mass = 20kg
So the Force is 20 x 10 = 200 N
Thus the work done = 200 x 5 = 1000 J
What else can I help you with?
How many joules is 10 newtons?
To calculate the energy in joules, we need more information such as the distance over which the force is applied. If we assume the force is applied over a distance of 1 meter, then the work done would be 10 joules (Work = Force x Distance).
How much force if 15 joules of work over 1 meter?
If 15 joules of work are done over a distance of 1 meter, the force applied would be 15 newtons. This is calculated using the formula: force = work / distance.
Work is measured in joules True or false?
True. Work is measured in joules, where 1 joule is equal to the work done when a force of 1 newton is applied over a distance of 1 meter in the direction of the force.
How do you convert newtons in joules?
Newton is a unit of force and joule is a unit of energy. To convert Newtons to Joules, you need to multiply the force in Newtons by the distance in meters over which the force is applied. The formula is: 1 Joule = 1 Newton * 1 meter.
What is work equal too?
Work is equal to the amount of force applied to an object multiplied by the distance over which the force is applied. It is a measure of energy transfer that occurs when a force acts on an object in the direction of the force. Work is typically measured in joules.

What does a high newton meter reading mean?
Unfortunately, you'll have to be more specific. If you are referring to a Newton meter (instrument), a high meter reading would indicate a high force or weight (not mass). Alternatively, a Newton-meter could be a Joules (a unit of work) or, if the force is applied as a rotational force, a Newton meter would be a unit of torque.
Why does a force meter contain a string?
A force meter contains a string because when a force is applied to the meter, it causes tension in the string. This tension is then measured by the force meter and displayed as a force reading, allowing for accurate measurement of the applied force.
What ia a force meter measured in?
usually in joules or lb/ft
What is the force that causes to stretch the spring in a force meter?
The force that causes a spring in a force meter to stretch is the tension or pull applied to the spring by an external force. The spring resists this force by elongating, allowing the force meter to measure the magnitude of the force being applied.
How much work does a 25 Newton force do to lift a potted plant from the floor to a shelf 1.5 meter high?
The work done is calculated by multiplying the force applied by the distance over which the force is applied. In this case, the work done to lift the potted plant would be 25 Newtons * 1.5 meters = 37.5 Joules.
How much is a energy in joules?
One joule is defined as the amount of energy transferred when a force of 1 newton is applied over a distance of 1 meter. It is a small unit of energy often used in physics for small-scale measurements.
A 200 lb man exerts 882 Newtons on earth how many Joules is that if he jumps a meter into the air?
To calculate the work done, we multiply force by distance, so in this case: Work = Force x Distance Work = 882 Newtons x 1 meter = 882 Joules Therefore, the man does 882 Joules of work when he jumps a meter into the air on Earth.
