What happens to the value of the Gravitational Potential Energy of a system of objects as the value of r increases?
The Potential energy decreases as r increases.
Is barrier potential temperature dependent?
Yes, it varies inversely, i.e. as temperature increases the barrier potential decreases. It decreases by 2mV for degree Celsius rise of temperature.
When a ball is falling what is the energy change?
As a ball fall downwards, it's velocity continuously increases, therefore the kinetic energy increases. As the height from the ground level decreases, the potential energy decreases. Further, the total mechanical energy remains constant throughout the motion.
Does mechanical energy of a coconut falling from a tree increases or decrease?
Kinetic energy increases whilst potential energy decreases. Total remains constant
If an object that moves faster does it have greater potential energy?
no. if an object moves faster its kinetic energy increases but at the same time its potential energy decreases.

The Potential energy decreases as r increases.
potential increases positively. This typically occurs due to?
an influx of sodium ions into a cell
Is barrier potential temperature dependent?
Yes, it varies inversely, i.e. as temperature increases the barrier potential decreases. It decreases by 2mV for degree Celsius rise of temperature.
How does potential energy turn to kenetic?
Potential energy turns into kinetic energy when an object at rest begins to move. As velocity increases, KE increases and PE decreases.
What is the relationship between a kinetic an potential energy?
When potiental increases, kinetic decreases and vice versa.
What is the final velocity of an object that decreases in kinetic energy and increases in potential energy?
Its final velocity will be zero when it reaches maximum potential energy.
As a ball falls downward what energy decreases and what energy increases?
As a ball fall downwards, it's velocity continuously increases, therefore the kinetic energy increases. As the height from the ground level decreases, the potential energy decreases. Further, the total mechanical energy remains constant throughout the motion.

Kinetic energy increases whilst potential energy decreases. Total remains constant
Does kinetic energy decreases as a box accelerates down an inclined plane?
Kinetic energy increases; potential energy decreases, because the object is now in motion
What happends to potential energy as a squashed ball regains its shape?
As the ball returns to its original shape, kinetic energy decreases and potential energy increases.
If an object that moves faster does it have greater potential energy?
no. if an object moves faster its kinetic energy increases but at the same time its potential energy decreases.
