The speed of an object is measured by calculating the distance it travels per unit time.
The formula in Physics for calculating speed is = distance/ time.
Since an object at rest is not covering any distance, the speed is always assumed to be 0 m/s.
Explanation:
The graphs show maximum gravitational potential energy for the pendulum and they correspond to positions #1 and #5.
Answer:
Quantum.
Explanation:
Quantum is defined as the discrete quantity of energy proportional in magnitude to the frequency of the radiation it represents.
It is the minimum amount of any physical entity (physical property) involved in an interaction or to put simply, it is defined as the minimum amount of energy that can be absorbed or released by matter.
Answer:
Kinetic Energy
Explanation:
Ang prinsipyo ay nagsasaad na ang enerhiya ay hindi maaaring malikha o masira, ngunit maaari lamang ma-convert mula sa isang anyo patungo sa isa pa. Ang tubig sa tuktok ng napakataas na talon ay nagtataglay ng gravitational potential energy. Habang bumabagsak ang tubig, ang enerhiya na ito ay na-convert sa kinetic energy, na nagreresulta sa isang daloy sa isang mataas na bilis.
To solve this problem we will apply the linear motion kinematic equations, which describe the acceleration as the change of speed within a unit of time. Later we will apply the concepts related to Newton's second law to find the Force made on the object.
First we need to figure out the average acceleration:
Through the kinematic equations of linear motion we know that
Applying Newton's Second Law
F = ma
Where,
m = mass
a = Acceleration
Replacing
Therefore the force is 36kN
