Can acceleration change with out increase or decrease speed?
yes the 3 types of acceleration are increased speed decrease speed or change in direction.
Why is retardation called negative acceleration?
retardation is nothing but the decrease in speed. so if the increase in speed can be taken as positive then for sure decrease in speed can be taken as negative acceleration.
The rate of change in the speed of an object is called?
Acceleration, it can be both increase and decrease in speed. .
How can you increase or decrease acceleration?
acceleration is a change in speed or direction, so to answer your ? you slow down, speed up or make a turn :]
How speed increase by applying force?
Applying more force in the direction of travel will increase the acceleration and therefore speed. If more force is applyed opposite to the direction of travel, acceleration will decrease.
If a ball rolls down a hill does its speed or acceleration increase?
If you roll a ball up a hill it undergoes negative upward and positive downward acceleration.
What is an increase of speed during a given interval of time?
Acceleration. Deceleration is a decrease of speed during a given interval of time.
How are acceleration and speed alike?
They are not alike but they are related. A positive acceleration means an increase in velocity (speed). A negative acceleration means a decrease in velocity. Velocity (speed) has the dimensions of distance / time. Acceleration has the dimensions of distance/time2 or velocity/time.
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.

Under what two conditions will you change velocity and thus acceleration or decceleration?
You either increase or decrease the speed
What 3 kinds of change motion are called acceleration?
1). increase of speed 2). decrease of speed 3). change of direction of motion
What 3 kinds of change in motion are called acceleration?
1). increase of speed 2). decrease of speed 3). change of direction of motion
