If it takes 100 N to move a box 5 meters what is the work done on the box
Everything in or on water pushes some water aside even if it's just a little bit What is this called
This is called "displacement", as the weight of water that moves
is equal to the weight of the object on the water. Heavier objects
displace more water. If the total weight of the object is greater
than the water displaced by its volume, it is denser than water,
and sinks.
Is momentum a vector quantity because it includes velocity which is also a vector quantity
yes, momentum is a vector quantity.
Spaceship 1 and Spaceship 2 have equal masses of 200 kg They collide Spaceship 1's final speed is 2 ms and Spaceship 2's final speed is 1 ms in the same direction What is their combined momentum
It takes 200 N to move a box 10 meters in 8 seconds How much power is required
In situations is mechanical energy conserved
It depends on the situation
In a collision a vehicle that rebounds off the object it trikes experiences less force than if it crumples assuming the time is the same in both situations
Spaceship 1 and spaceship 2 have equal masses of 300kg spaceship 1s has a speed is 0 ms and spaceship 2 has a speed of 4 ms. they collide and stick together. what is their speed
