What makes your vocal cords vibrate?
air molecules push back and forth
What type of energy is the movement of waves that vibrate air molecules?
sound
Air resistance is created by?
air molecules in the way of falling objects
Air molecules speed up the movement of objects in motion?
The friction (with the air molecules) would slow it down.
How does heat make molecules move?
The heat energizes the molecules.The molecules of air will move here and there as they are free. Molecules of solids vibrate at there place.Due to heat the molecules get energized that is the main thing.
Does sound waves make air molecules vibrate?
vibrations make air molecules move
Why can only solids vibrate but liquid and gases can't?
Liquids and gases can vibrate. In fact sound is the vibration of air molecules.
Why does sound travel through the air?
Sounds vibrate the air molecules, when the vibrating molecules reach your ear, you ear the sound, there are no molecules in space, thus no sound in space

How does a fork create sound?
By vibrating ('oscillating') and making the surrounding gas (air) molecules vibrate, which makes our ear drums or microphone membranes vibrate.
Air molecules speed up the movement of objects in motion?
The friction (with the air molecules) would slow it down.
What causes the warm air to rise and the cold air to sink?
The warmer the air is, the more energy the molecules have. The more energy the molecules have, the more they vibrate. When the molecules vibrate, they bounce into each other and push apart from each other, hence the warmer the air is, the less dense it is (number of molecules per unit volume). Colder air has less energy which means more molecules can fit into one space because they are not bouncing off each other.
How does heat make molecules move?
The heat energizes the molecules.The molecules of air will move here and there as they are free. Molecules of solids vibrate at there place.Due to heat the molecules get energized that is the main thing.
Sound waves are waves of vibrating what?
Sound waves are waves of vibrations. When you speak, you vibrate a few air molecules, which vibrate and hit other air molecules, then more and more. when the molecules in your ear vibrate, you hear sound. But really, you feel the vibrations. Then why do we say hear, instead of feel? Because we are already used to saying hear. you wouldn't come to your friend and say, "Speak louder! I can't feel you!"
Collisions of atoms and molecules in air with objects?
its gas pressure
