Understanding the Work-Energy Theorem

Click For Summary
The discussion clarifies key definitions related to the Work-Energy Theorem. Work is defined as energy transferred when forces between two objects interact. The formula for work done by a force is established as W = F*Δs, indicating that work equals force multiplied by the distance moved in the direction of the force. Additionally, work done by a gas is defined as W = p*ΔV, where pressure is multiplied by the change in volume. Overall, the conversation reinforces the foundational concepts of work in physics.

Are the following definitions correct?

  • Work done as energy transferred
The energy transferred when the forces between two objects interact

  • Work done by a force
Work done = force x distance moved in the direction of force applied (W=F*Δs)

  • Work done by a gas
Work done = pressure x change in volume of gas (W=p*ΔV)

Did you just... I mean, you answered the 2nd and the 3rd question yourself.
 
When a force is applied to a body and the body is displaced from its original position then work is done.

Thread 'Using energy principles to find equilibrium depth of floating object'

For fun I was trying to use energy considerations to determine the depth to which a solid object will sink in a fluid to reach equilibrium. The first approach that I tried was just to consider the change in potential energy of the block and the fluid as the block is lowered some unknown distance d into the fluid similar to what is shown in the answer to this post. Upon taking the limit as the vessel's cross sectional area approaches infinity I have an extra factor of 2 in the equilibrium...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'A remark on problem about trajectory of a projectile in the atmosphere'

This is just to share some teaching experience. A problem about trajectory of a projectile in the atmosphere is very well known. The trajectory has a vertical asymptote. This fact is easy to obtain by using the stability theory. Consider equations of motion. Let ##\boldsymbol v=v_x\boldsymbol e_x+v_y\boldsymbol e_y## be the velocity of the projectile relative the standard Earth fixed frame ##xy## with ##y## directed upwards. The second Newton ##m\boldsymbol {\dot v}=m\boldsymbol g-\gamma...
