An object's speed changes whenever the rate of change between the distance the object travels and the time it takes to travel that distance changes.
Do not confuse speed with velocity; speed is scalar, and velocity is vector. Velocity can change when speed remains constant.

What happensto the speed of an object if a unbalanced force acts on it?

Velocity is the change of speed and or direction of an object?
FALSE. Acceleration is the change of speed and/or direction of an object.
What is change in the speed of an object?
A change in the velocity is produced by a force acting on the object. A change in velocity means a change in speed or direction (or both).
Can speed change?
Yes. In general, the speed of any object can change.
The term used to measure a change in speed of an object is?
Acceleration is the rate of change of the velocity (speed) of an object. Acceleration is the derivative of the speed vs. time function.
If the speed of an object does not changed then the object is traveling at a?
If speed does not change then the object is moving with constant speed. when object moves in a circle its speed does not remains constant. Speed of object remains constant only if it moves along linear path.
If the speed of an object does not change the object is traveling at what speed?
there's four speed. There are constant speed, average speed, increasing speed, and decreasing speed. choose one of them
Is motion the change in speed?
no motion is the movement itself, the change in position of an object with respect to time. rate of change of speed is acceleration. change in speed is just change in speed.
If the speed of an object does not change the object is traveling at a?
. . . constant speed, although its velocity may easily be changing.
What is a force that can cause an object to change its speed and direction?
A basic physics answer for this is that a net force (or unbalanced force) will cause an object to accelerate, that is, cause the object to change its speed and/or direction.
What does newtons first law say about a moving object if the forces on the object are balanced?
The object will maintain its speed and direction or the object will not change its speed or direction.
What does it mean for an object to have constant speed?
the object's speed doesn't change
Which of these would change the direction of an object but not affect the object's speed?
Circular motion would change the direction of an object but would not affect the object's speed.
What is the average speed of the object over the time interval 6s to 12s?
The average speed of an object is its; Change in position/Change in Time = Distance/Time
What happens to the velocity of an object even if the speed of an object remains constant?
Velocity can change even if speed is constant.
Traveling without changing speed?
When you (or an object) travel without changing speed, then you have constant velocity (speed). This means there is no change in speed (acceleration) when you (or an object) is traveling.
If you change the velocity of a moving object you change its?
Speed or direction or both.
What is the difference of accelaration and decelaration?
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-
What is a force that can cause an object to change speed and or direction?
any external unbalanced force will cause an object to change its velocity, ie. Speed and/or direction of motion
Which is not a way to accelerate an object-?
One way to not accelerate an object is by trying to reduce its speed. In physics, a change in speed or in direction is called acceleration. One way not to accelerate an object is to change its name.
