If they have room to travel (e.g., you shine the flashlight towards the sky), they can travel on indefinitely.
No, when you turn on a flashlight, the emission of light does not exert a force on the flashlight itself. The light is simply released in the form of photons, which travel in straight lines until they interact with something else.
Photons travel outward from a light bulb in all directions due to their wave-particle duality. As the light bulb emits electromagnetic radiation, photons are released and propagate in a straight line until they interact with surfaces or particles. The photons then transfer their energy to these surfaces, allowing us to see the light emitted from the bulb.
Photons have no charge, no rest mass and travel at the speed of light throuh a vacuum. Electrons have a charge of -1, have rest mass and are part of atoms.
As particles photons travel in a straight line unless they are diverted by reflection, refraction, or a magnetic or gravitational field. Note that when it comes to gravity it can also be represented that the light continues in a straight line - but the space it travels through is curved so its path appears curved to the outside observer.
Photons do not travel through time. This is due to the fact that the faster you travel through space, the slower you travel through time. In other words, if an object is standing still, it is traveling at the speed of light through time, and since a photon travels at the speed of light through space, it is not traveling through time. -- Asker here, I hope no one minds me editing in to expand on the question/answer given. Surely the answer must be more complex. If a photon does not travel through time, then that could potentially violate/invalidate causality.
The light leaving a flashlight when it is turned on and then off will tend to move in a straight line. The problem is that there is air that the light will have to move through. The air will scatter or even absorb the photons. Eventually all the photons will be scattered and absorbed. If the experiment was conducted in outer space, the photons would travel a great distance as there is little in the way of particles to scatter the photons. Here on earth, the atmosphere would absorb the energy as there is relatively little of it released from the flashlight.

In a straight line. At the speed of light.
No. All photons travel at the speed of light.

Photons travel outward from a light bulb in all directions
the photons travel outward from a light source in all directions.
No, the speed of light in a vacuum is constant for all photons regardless of their energy. Higher energy photons have a higher frequency and shorter wavelength, but they still travel at the speed of light.

Yes
Photons do not experience time because they travel at the speed of light, which means time does not pass for them.
Individual packets of light are called photons. Photons are the basic unit of light and do not have mass, allowing them to travel at the speed of light.
