AI Thread Summary
Force is defined in physics as an interaction that causes an object to accelerate, often experienced as a lift, push, or pull. To determine if a force is acting, one can observe changes in motion or acceleration of an object. Forces can result in various effects, such as changing an object's speed, direction, or shape. Newton's Second Law provides a comprehensive explanation of these concepts. Utilizing a textbook can clarify these fundamental principles further.

"In physics, force is what causes a mass to accelerate. It may be experienced as a lift, a push, or a pull" - wikipedia
 
No offense, but these are pretty basic definitions that you could find easily with a little effort. Do you have a text? What does it say about forces?

I'll give you a hint: If you can find Newton's Second Law in your text, it should answer all three of these for you.

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
