What is kinetic energy
Kinetic energy is the energy that an object has due to its
motion or movement. For instance if a car drives into a wall the
energy of its movement is what destroys the wall, That energy is
kinetic energy.
Note: Heat is also a form of Kinetic energy because heat is the
movement (vibration energy) of atoms or molecules.
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.
Is momentum a vector quantity because it includes velocity which is also a vector quantity
yes, momentum is a vector quantity.
According to the Impulse-Momentum Theorem what does impulse equal
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
How much work must be done on a 5 kg snowboard to increase its speed from 2 ms to 4 ms
Spaceship 1 and Spaceship 2 have equal masses of 150 kg Spaceship 1 has a speed of 0 and Spaceship 2 has a speed of 6 They collide and stick together What is their speed
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
Whih of the following is not a reason why gravity is important in our lives
It keeps water molecules together in a cup.
What do we call a collection of matter that does not interact with anything else in the universe
An isolated system I think
