Work, in the scientific sense, is defined as force applied over a distance and is measured in the International System (SI) in Joules (J) which are also known as Newton meters (Newtons being the SI unit of force and meters being the SI unit of distance).
For example, if I use 20 Newtons to push a box across the floor 3 meters, the work I exerted is:
Work (J) = 20 N X 3 m
Work (J) = 60 N m
Work = 60 J

How much work is exerted when a 100N force is applied over 5m?
Work is force times distance - assuming the force is applied in the same direction as the movement.
If you know the objects mass and acceleration you can determine the net force being exerted on the object?
True
How much work was done if a force of 15 N is exerted over a distance of 6 m?
Work = force x distance = 15 x 6 = 90 joules
How does the steepest of a slope affect work?
The steeper the slope, the more work (force) has to be exerted.
If you know an object’s mass and acceleration you can determine the net force being exerted on the object?
True!. Sierra Ambrosio"))
Is cycling to work much healthier than travelling by car?
Yes it is much healthier but only if you don't get over exerted.
Are mass and velocity forces?
No!! Force is how much work is being exerted on an object. NOT how much grav. pull (mass) or how much its accelerating (velocity)!
Does blood pressure determine the force exerted by the blood on the walls of the arteries?
Yes it does.
How much work is exerted when a 100N force is applied over 5m?
Work is force times distance - assuming the force is applied in the same direction as the movement.
The measuring of how much gravitational force is exerted on an object is called?
The measure of how much gravitational force is exerted on an object is called?
If you know the objects mass and acceleration you can determine the net force being exerted on the object?
True
What instrument measures how much work is being done to move an object?
A spring scale and a meter stick. Spring scale may be used to find force exerted. Meter stick finds distance through which force was exerted.
How much work was done if a force of 15 N is exerted over a distance of 6 m?
Work = force x distance = 15 x 6 = 90 joules
How does the steepest of a slope affect work?
The steeper the slope, the more work (force) has to be exerted.
You remind your Airmen that the four basic factors that determine the degree of heat stress exerted by the environment are?
the answer is f
What are Advantages and disadvantages of mechanical systems?
Advantages: -make work much more easier to complete -make work faster to complete -less energy required -less exerted force required Disadvantages: -may malfunction and corrupt the entire system
