Which form of energy is due to the movement of electrons
Which of the following expressions are correct for impulse
F the triangle thingy and t
the triangle thingy then p
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.

What the the two main states of mechanical energy
Potential energy and Kinetic energy
Is momentum a vector quantity because it includes velocity which is also a vector quantity
yes, momentum is a vector quantity.

In situations is mechanical energy conserved
It depends on the situation
How much work must be done on a 5 kg snowboard to increase its speed from 2 ms to 4 ms
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
