speed cannot as it is just a magnitude, however as velocity relates both magnitude and direction, and direction can be negative, technically you can have a negative velocity.
see speed cannot de negative se speed = distance / time and neithr distance nor time can be negative they r always positive so speed cannot be negative but velocity can be negative
In that case, basically no force acts on the particle, and the particle moves at a constant speed. This constant speed may, or may not, be zero.
Sounds like a trick question. The answer is no. Speed is a scalar with magnitude only and velocity is a vector with magnitude (speed) and direction. So If traveling with velocity in a straight line it has speed..
The linear speed of the particle moving on a circular track can be found using the formula v = r * ω, where v is the linear speed, r is the radius of the circle, and ω is the angular speed of the particle.
A beta particle is a negative electron. A positive electron is a Positron.

Speed in science means vector (direction and velocity). Any force which lessens the vector can be considered negative speed. A spacecraft's retro rockets are a good example.
Light is currently considered to be the fastest known particle(s) in existence. There are theoretical particles that can function well past the speed of light. One example of such theoretical particle is the Tachyon.
In that case, basically no force acts on the particle, and the particle moves at a constant speed. This constant speed may, or may not, be zero.
Yes, it is possible. For example, if a particle moves back and forth between two points with different speeds, such that the time spent at each point is unequal, the average speed would not be zero even though the particle's speed is zero at each point.

The speed of a gamma particle is approximately the speed of light, which is around 299,792 kilometers per second in a vacuum.
A non-relativistic particle is any particle not traveling at a speed close to the speed of light. This is not a property of particular type of particle; any particle may in general travel at any speed (below the speed of light). An exception are particles which are massless such as photons and gluons, these MUST travel at the speed of light.
