What is momentum?
Inertia in motion, or more specifically, the product of the mass of an object and its velocity
What is the unit used for momentum?
Kgs
What is work?
The product of the force exerted on an object and the distance the object moves ( in the same direction as the force)
What is Conservation of energy
What is the formula of momentum?
Mass x velocity
What is the formula for Power?
Work done / time interval
What is the work energy theorem
Work done by all forces equals the change in the kinetic energy.
What units do both Work an Energy use?
Joules
Who is independent?
Tyler
What is Impulse-Momentum-Relationship
The greater the impulse exerted on something, the greater will be its change in momentum
What is Efficiency?
How effectively a device transforms or transfers useful energy
What is Machines?
A device for multiplying force or changing the direction of force
What is Conservation of Momentum
The concept that momentum is conserved when no external force acts is elevated to a central law of mechanics.
What is Potential Energy?
Such stored energy
Who is the best?
Tyler
What is Energy?
ability to do work
What is the formula of impulse?
The quantity force x time interval
What is the Law of Conservation of Energy?
In the absence of external work input or output the energy of a system remains unchanged. Energy cannot be created or destroyed
What is the Formula for work?
Force x distance
What is power?
A measure of how quickly work is done. The rate at which energy is changed from one form.
What is the formula for Machines
(Force x distance ) input = (force x distance) output
What is Kinetic Energy
The energy associated with a moving body by virtue of its motion alone
What is the formula for Efficiency ?
Work done / energy used x 100%
What is impulse?
The product of force and contact time
What is the formula for Kinetic Energy?
1/2 Mass x speed2
