This question comes with this set of answer choices:
A.Kinetic energy and potential energy are equal when the bob is at its resting point.
FALSE: BECAUSE AT REST KINETIC ENERGY IS ZERO AND POTENTIAL ENERGY IS MAXIMUM.
B.Kinetic energy and potential energy are equal when the bob is halfway between its resting point and its maximum amplitude.
TRUE: AT REST POTENTIAL ENERGY IS MAXIMUM AND KINETIC ENERGY IS ZERO, AS THE PENDULUM MOVES THE KINETIC ENERGY INCREASES AND THE POTENTIAL ENERGY DECREASES. IN AN INTERMEDIATE POINT BOTH ENERGIES ARE EQUAL.
C.Kinetic energy and potential energy are equal when the bob is at its maximum amplitude.
FALSE: THE MAXIMUM AMPLITUD IS WHEN THE PENDULUM BECOMES AT REST.
D.Kinetic energy and potential energy are equal when the bob is halfway between its pivot and its minimum amplitude.
FALSE: THIS DESCRIPTION OF THE MOTION DOES NOT MAKE SENSE AS THE PENDULUM IS NEVER HALFWAY BETWEEN THE ITS PIVOT AND ITS MINIMUM AMPLITUDE.
Answer: B.Kinetic energy and potential energy are equal when the bob is halfway between its resting point and its maximum amplitude.
The answer is 0.245N.
<h3>What is kinetic energy?</h3>
- A particle or an item that is in motion has a sort of energy called kinetic energy. An item accumulates kinetic energy when work, which involves the transfer of energy, is done on it by exerting a net force.
- Kinetic energy comes in five forms: radiant, thermal, acoustic, electrical, and mechanical.
- The energy of a body in motion, or kinetic energy (KE), is essentially the energy of all moving objects. Along with potential energy, which is the stored energy present in objects at rest, it is one of the two primary types of energy.
- Explain that a moving object's mass and speed are two factors that impact the amount of kinetic energy it will possess.
(b) 0.100
For the block on the left,
∑=
–0.308N+0.245N=(0.250kg)a
a=−0.252 if the force of static friction is not too large.
For the block on the right, ==0.490N. The maximum force of static friction would be larger, so no motion would begin, and the acceleration is zero
