AP Physics 1 : Work

Study concepts, example questions & explanations for ap physics 1, all ap physics 1 resources, example questions, example question #1 : work, energy, and power.

None of the other answers here

The most important part of this question is noticing that it asks how much work has been done on the bar, not how much work the bodybuilder has exerted. Therefore we can use the work energy theorem:

Since the bar is initially at rest and returns to rest, the net work on the bar is zero. All of the energy exerted by the bodybuilder is counteracted by gravity.

Think about the system practically. Comparing the initial and final states, the bar is in the exact same position.

Since the truck is traveling at a constant rate, we know that all of the power exerted by the truck is going into a gain in potential energy. The power exerted will be a function of the change in potential energy over time. Therefore, we can write the following formula:

We can substitute velocity into this equation:

We have values for all of these variables, allowing us to solve:

Example Question #3 : Work, Energy, And Power

Example Question #4 : Work, Energy, And Power

Juri is tugging her wagon behind her on the way to... wherever her wagon needs to go. The wagon repair shop. She has a trek ahead of her--five kilometers--and she's pulling with a force of 200 newtons. If she's pulling at an angle of 35 degrees to the horizontal, what work will be exerted on the wagon to get to the repair shop? 

Work exerted on an object is equal to the dot product of the force and displacement vectors, or the product of the magnitudes of the vectors and the sin of the angle between them:

The work exerted on the wagon in this problem is thus:

Example Question #5 : Work, Energy, And Power

Since this question refers to work done by nonconservative forces, we know that:

In our case:

Example Question #6 : Work, Energy, And Power

The work done by a centripetal force on an object moving in a circle at constant speed is __________ .

equal to the force exerted 

equal to the kinetic energy of the object

equal to the force exerted multiplied by the displacement

Recall that work can be defined as:

Example Question #7 : Work, Energy, And Power

Raul is pushing a broken down car across the flat expanse of the Mojave to his shop.  

If his shop is three kilometers away and he pushes with a Herculean force of one thousand newtons in the direction of his shop, how much work will be done on the car?

Work is given by the dot product of force and displacement. Since both the force and displacement are in the same direction in this problem, work is simply the product of the two:

Example Question #8 : Work, Energy, And Power

Example Question #9 : Work, Energy, And Power

we can use the evidence provided by the problem to solve for distance.

Example Question #1 : Work

A 50kg man pushes against a wall with a force of 100N for 10 seconds. How much work does the man accomplish?

This saved my life

I wasn't paying attention in class so I forgot what to do so I panicked so I started searching for an app that can help me. I found a few and installed but they kept telling me it was a word problem and that they can't solve it so I searched and searched until this app came I'm like this is like those apps but let's give it a try and then it said can solve every subject so I'm ok that's a good sign and then I finished my homework so try this app today. Trust me you won't regret installing this life saving homework app

I had no problems with it at first. The first few questions were free and I didn’t realize there was a limit on how many questions you could ask it. I ran out of questions quickly. It is absolutely disgusting how so many of these Ai apps expect large sums of money when all you want to do is study and learn. ESPECIALLY the amount they ask for. Some ask for 10-20$ a month just to talk to a BOT that may not even give you accurate/quality answers. Worst part is they expect you to make an account using apple so you can’t even make a new account or get anymore free questions. I deleted the app almost instantly. This app is no different than any other greedy AI app. Until it’s free or at least gives you more free questions I will be steering clear. Good bye.

The best math helper

This is the best thing I’ve ever seen the other things like Gauth, AI and Chat AI and chat to BT they don’t show me how to do this properly. Whenever I take a picture it shows me the wrong answer and I’ve told them multiple multiple times and it still doesn’t give me the right answer but this actually gives you the right answer. I thought it would be one of those scams, we give you the wrong thing, but it gives you the actual best answer you can get
