1. Distance: The distance an object travels over a certain period of time determines its speed. The farther the object travels, the faster it is going.

2. Time: The time it takes for an object to cover a specific distance impacts its speed. The less time it takes, the faster the object is moving.

3. Displacement: Displacement is the change in position of an object. The greater the displacement over a given time, the faster the object is traveling.

4. Velocity: Velocity is a vector quantity that includes both speed and direction. An object can have the same speed but different velocities if they are moving in different directions.

5. Acceleration: Acceleration is the rate of change of velocity. If an object is accelerating, its speed is changing.

Here are some additional factors that can influence the speed of an object:

* External forces: Forces like gravity, friction, and air resistance can affect an object's speed. For example, a ball thrown upwards will slow down due to gravity.

* Mass: The mass of an object can affect its speed. A more massive object requires more force to reach the same speed as a less massive object.

* Momentum: Momentum is a measure of the mass and velocity of an object. Objects with higher momentum tend to be more difficult to stop and therefore can have a greater impact on their speed.

In summary: The speed of an object is a complex interplay of factors that involve distance, time, displacement, velocity, acceleration, and external forces.
