true
Yes they do
Newtons 1st law, "An object in motion will stay in motion unless acted upon by another force." Basicly the photons travel through space gradually spreading out as they hit different particles.
The centripetal force is what draws the object towards the centre. The centrifugal force is what draws the object away from the centre. Generally when one speaks of centrifugal force, one means only that it takes the centripetal force to keep moving the object out of its straight direction of travel. If you remove the centripetal force in such an example, such as when the object is in a circular orbit around another body, then the result will be that the orbiting body will continue traveling in a straight line at a tangent to the circular path it had been following.
The light moves from the source in a straight line to an object and then moves into the back of your eye to your retina.
A particle accelerator is used to make particles travel very fast using magnetic waves. The particles are then collided with other particles to see what happens.
Light can travel through undistorted
yes, but since there are atoms and molecules in the atmosphere they bounce off of them and go in a different direction.
there are no particles to collide
Gas particles move randomly in all possible directions and travel in a straight path.
Heat=energy. The higher the heat, the higher the energy. Particles travel faster because they have more energy.
That is the result of inertia; an object in motion will remain in motion until some force alters that motion. Field free regions do not have forces acting on the particles in those regions. All forces are associated with fields.
Sound can't be heard on the moon because sound need a medium to travel and particles to collide each other in order to travel. since in a vaccum (space) you do not have air, meaning no particles, sound can't be heard on the moon.
when particles collide with each other and with other object in their path it happens when sediments is transported from its source to where it is deposited. these collision can cause the particles to change size and shape. angular and uneven rocks are when particles that have moved long distances from the source tends to be more rounder and smoother. the farther sediments travel from its source the finer and smoother the particles of sediments become.
no

Sound travels slowly through gas because the particles in a gas are further away then the particles in a solid or a liquid. This makes it take longer for the sound waves to travel through the particles in gases because it takes longer for them to collide with each other; this makes it take longer for the particles to pass on the sound vibration.
Sound is produced due to vibration. Sound needs medium such as air to travel. When an object vibrates, it sets neighbouring particles of medium to vibrate. These particles oscillate back and forth and reach our ears.
It would not collide with planet earth. It would travel in a straight line away from the earth perpendicular to the line between the earth and the moon.
