Any change of velocity, including a decrease of speed, is described and measured as acceleration. Assuming the velocity and acceleration vectors point in the same direction, then in the case of decreasing speed, the magnitude of the acceleration is a negative value. Negative acceleration is often called deceleration, but that is just a special case of acceleration.

What does the term "acceleration" mean in physics?

Acceleration in physics refers to the rate at which an object's velocity changes over time. It can be an increase or decrease in speed, or a change in direction.

How does retardation in physics occur?

In physics, retardation refers to a decrease in the speed of an object. This can occur due to forces like friction, air resistance, or gravity acting in the opposite direction to the object's motion, causing it to slow down. Retardation is the opposite of acceleration, where an object's speed increases.


What is the speed of an object plus its direction?

The speed of an object plus its direction is called velocity. Velocity is a vector quantity that combines the object's speed (magnitude of the velocity) and its direction of motion.


What 3 kinds of change motion are called acceleration?

1). increase of speed 2). decrease of speed 3). change of direction of motion


What is study of velocity speed and acceleration called?

The study of velocity, speed, and acceleration is called kinematics. Kinematics is a branch of physics that deals with the motion of objects without considering the forces causing the motion.


What is the decrease in speed?

When speed changes, the rate a which you are going (ex: 22 miles per hour) changes. Direction changes when the direction(ex: north, south, east, west) changes. Any change in speed or direction of motion is known as 'acceleration'.


Can acceleration change with out increase or decrease speed?

yes the 3 types of acceleration are increased speed decrease speed or change in direction.


Can weight in the trunk of a car make the car decrease in acceleration speed?

YesF=maForce = mass x acceleration.A well know physics equation. So any increase in force (power) or any decrease in mass (junk in your trunk) will increase your acceleration.


As the speed and length of wave decrease what happens to the wave?

As the speed and length of a wave decreases, the frequency of the wave remains constant. This means that the wave will experience a decrease in wavelength, which is inversely proportional to the decrease in speed. The energy of the wave will also decrease.


How is speed velocity acceleration related?

Speed is the rate of motion usually expressed as distance traveled per unit of time.Velocity is the rate of change of position. Both speed and direction are required. Acceleration is the rate of change in velocity. In common speech, acceleration is only for an increase in speed; a decrease in speed is deceleration. In physics, any increase or decrease in speed or change of direction is referred to as acceleration.
