685N and your belongings have a weight of 915N. How much work does the elevator do in lifting you and your belongings 5 stories (15.2m)? Solution: W= (685N+915N) (15.2m) W= (1600N) (15.2m) W= 24‚320Nm or J Section 2 Gravitational Potential Energy: 6. A 0.15kg ball is thrown 9.0m straight up. What is the work done by the gravitational force? And what is the change in PE? (Notice anything?) Solution: PE= m*a*h PE= (0.15kg) (9.8 m/s^2) (9.0) PE= 13.23 kg m^2/s^2 or J - The

POTENTIAL ENERGY DIAGRAM In physics the terms of mechanical energy usually refers to Potential energy (U) and Kinetic Energy (K). In the absence of non-conservative‚ or dissipative forces‚ these energies obey the law of conservation of energy‚ or ΔU + ΔK = 0. That is‚ when a system is only acting under the influence of conservative forces its total energy content never changes‚ the energy just converts between forms. At any point in the cycle‚ the total energy is constant‚ U + K = Umax = Kmax

And the projectile concepts of the effect of changing potential into kinetic energy and for me to demonstrate my ability to apply elastic potential energy to a scientific investigation. What am I going to do and what will it prove: I am going to use an elastic band and release it from different tensions I will then measure how far it ‘flies’. Doing this will tell me the relationship between force‚ potential energy and kinetic energy.

POTENTIAL EFFECTS OF DISCRIMINATION. TASK 3: In looking at this task‚ we have already studied the first part of the topic at the beginning of the Unit. Forms of Discriminatory Practice exist‚ in the form of: Prejudice‚ Stereotyping‚ Labelling‚ Bullying‚ Abuse‚ Lack of choice‚ Infringement of Rights‚ and Covert/Overt abuse of Power. Do we accept that these forms of discrimination exist? What do you think……as maybe you do not agree? Discrimination can be understood as damaging the individual
