one is positive one is negitive.
Acceleration is to speed up. Deceleration is to slow down.
Acceleration is a vector quantity, as it has both magnitude and direction.
Acceleration is an increase in change in speed over time of an object, and deceleration is a decrease in the change in speed over time of an object. -aerol-
Motion is about speed of location change, acceleration is about speed change.
It means to reduce speed. It is the opposite of acceleration. If someone driving presses the brake pedal or takes their foot off the accelerator, the car will start to slow down which is deceleration.
Velocity . . . what speed and direction something is moving. Acceleration . . . how fast the speed and/or direction of its motion are changing.
Technically no. "Deceleration" is a term used by many people to describe an object slowing down. However, the physics definition of acceleration is the change of velocity or direction. This means that acceleration can mean either speeding up, slowing down, or changing direction. While it is understood what "deceleration" means, it is a misused term.
In circular motion, tangential acceleration and centripetal acceleration are related but act in different directions. Tangential acceleration is the rate of change of an object's tangential velocity, while centripetal acceleration is the acceleration towards the center of the circle. Together, they determine the overall acceleration of an object moving in a circle.
Yes. The moon is continuously 'falling' around the Earth, and the acceleration is due to the gravitic attraction between them. This is a different acceleration than the "go faster and faster" kind.
Gravitational acceleration is simply acceleration due to gravity.
Angular acceleration is the rate of change of angular velocity of an object, while radial acceleration is the component of acceleration directed towards or away from the center of rotation. They are related but describe different aspects of an object's motion in a rotational system.
The relationship between acceleration and mass is that acceleration is inversely proportional to mass. This means that as mass increases, acceleration decreases, and vice versa.
