This is one definition of acceleration (including deceleration) - any change in the speed of motion of a moving object, or in the direction of its motion. Motion is a vector value with both speed and direction.

What represents the velocity of a moving object?

Speed and direction of the object. Speed is but an object moving in a straight line, while velocity is a change in direction of the object i.e. 45kph in a nnw 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.


How can a force effect a moving object?

It can change its speed or direction.


What is the term for a change in speed or direction of a moving object?

A change in the speed or direction of a moving object is called acceleration. Slowing down is also acceleration, not deceleration as is commonly used for such a situation.



What is the 6 things that forces can do?

Force can: * Move an stationary object * Speed up * Slow down a moving object * Change the direction of a moving object * Stop a moving object * Change the shape of an object Hope this is useful to you!



The speed and direction of a moving object is called?

The speed and direction of a moving object is called its vector; velocity



What happen to the speed of moving object when it is pushed in the direction of motion?

When a moving object is pushed in the direction of its motion the speed of the object increases


Can a unbalanced force change an objects motion?

An unbalanced force can: change the speed an object moves at change the direction an object is moving cause an object to start/stop moving


How can an object moving at a constant speed have a nonzero acceleration?

Because an acceleration is a CHANGE in speed or direction.



Why do we say an object moving in a circle at a constant speed is accelerating?

Because "acceleration" is defined as any change in the speed or direction of motion,and the direction of motion of an object moving in a circle is changing constantly.


Speed and direction an object is moving?

The speed and direction of an object together are called the object's velocity.


Which of these determines the speed and direction of moving object?

The forces acting on the object determine the its direction. Velocity tells you the speed and direction of an object.


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 the defintion of velocity?

Velocity is a vector quantity that describes the speed and direction that an object is moving. It is the same as "speed" except that it includes the direction of the object as well. Speed is the rate of change of distance.


What is the speed of an object moving on a particular direction?

The speed of an object moving in a particular direction is called the velocity and it's a vector, that is, it has magnitude and direction. Speed is the scalar part of velocity.



What Happens to an objest that is moving when the net force of zero?

When the net force on an object is zero, then the speed and direction of the object's motion don't change. The object can certainly be moving, even at a high rate of speed. That doesn't require any force. But without force, the speed and its direction can't change. The object continues moving at a constant speed, in a straight line.


What effect do balanced forces have on a moving object?

Balanced forces will not change the velocity - speed and direction - of a moving object. the object will continue to move in the same way.


Can an object be moving if acceleration is zero?

Yes. Acceleration is defined as a change of speed and/or direction of motion. If the speed and direction of motion are constant, then there is no acceleration.


Includes both the speed of an object and the direction its moving?

Velocity describes the speed and direction of travel of an object.
