Answer:
a) the elastic force of the pole directed upwards and the force of gravity with dissects downwards
Explanation:
The forces on the athlete are
a) at this moment the athlete presses the garrolla against the floor, therefore it acquires a lot of elastic energy, which is absorbed by the athlete to rise and gain potential energy,
therefore the forces are the elastic force of the pole directed upwards and the force of gravity with dissects downwards
b) when it falls, in this case the only force to act is batrachium by the planet, this is a projectile movement for very high angles
c) When it reaches the floor, it receives an impulse that opposes the movement created by the mat. The attractive force is the attraction of gravity.
Answer:
B
Explanation:
bIrish Kaleb picked Lucian usual
Potential energy E = mgh
m mass
g gravitational constant
mg = weight (in Newton)
h = height (in meter)
Answer:
when work is done by an applied force, the objects energy will change. in this interactive, does the work cause a kinetic energy change or a potential energy change?
The work done cause the potential energy to change because the body was initially at rest before work done, it was after a force is applied that there is energy changes from potential to kinetic energy
