negative acceleration, also deceleration
When an object's velocity decreases, it is referred to as deceleration. Deceleration occurs when the object's speed decreases over time.
condensation and the speed decreases
Subsonic
When a gas changes into a liquid, it is called condensation. During condensation, the speed of the gas molecules decreases as they lose energy, allowing them to come together and form a liquid.
Instantaneous Speed.
The study of speed is called kinetics. It involves analyzing the motion of objects and the factors that affect their speed.
Speed and direction is called velocity.
Terminal velocity if it has reached its top speed. Or obviously constant speed.
When a gas changes into a liquid, it is called condensation. The speed of the gas molecules decreases during condensation, as they lose kinetic energy and come closer together to form a liquid.
If speed increases, or if the moving object curves up or down or to the right or to the left, or if speed decreases, any of these events is called "acceleration".
The speed is v and the starting speed is v0.
When the distance between objects decreases, the electrical force between them increases. This is because the force of attraction or repulsion between charged objects is inversely proportional to the square of the distance between them, following Coulomb's law. Thus, as the distance decreases, the force strengthens.
