Yes, pushing against a brick wall would require force and displacement, which are the two components of work. You would be exerting energy to apply a force on the wall, but if the wall doesn't move, there would be no work done on the wall.

Can you lean against a wall if frictional forces are absent?

No, you would not be able to lean against a wall if frictional forces are absent because friction is what allows you to exert a normal force against the wall, which then supports your weight. Without friction, there would be nothing to prevent you from sliding down the wall.


Which would weigh more a brick made of iron or the same size brick made of lead?

Oh, dude, let me break it down for you. So, like, a brick made of lead would weigh more than a brick made of iron because lead is denser than iron. It's all about those atomic weights and stuff, you know? So, if you're looking to impress your friends with some random trivia, there you go!


Which would weigh more a brick made of iron or the samesize brick made oflead?

A brick made of lead would weigh more than a brick made of iron of the same size. This is because lead is denser than iron, meaning it has more mass packed into a similar volume.


Is it true that rolling a cart up a ramp is an example of doing negative work?

No, rolling a cart up a ramp is an example of doing positive work, as energy is being transferred to the cart to lift it against gravity. Negative work would be done if the cart were rolling down the ramp, as energy would be lost against gravity.


Where does sound travel faster wood or brick?

You mean which one does it travel faster in? It would be a brick because of how tightly packed the molecules in the brick are together. Wood, which is a lot more fragile that brick, does not allow sound to travel through it as fast.

What is a non-example of newton's 3rd law of motion?

Say a 14 year old girl was at a construction site and she was asked to move something like a 10,000 pound brick( one brick). She would be acting on it as the unbalanced force but they would still not change their position. so to say the girl would be doing everything she could to move that brick but the brick would still be in that same spot so the unbalanced force (the girl) would be acting on the thing that was at rest but it wouldn't move. so the unbalanced force would not really be acting on the thing at rest; even though the unbalanced force was doing something to the brick. ( just think about it and you will eventually get it...just imagine in your head...)
