What changes speed and direction?
Velocity is defined as a vector quantity representing both speed and direction. Acceleration is defined as the rate at which velocity changes. The acceleration of an object changes when it is acted upon by an unbalanced force.
What is something that changes motion in an object?
A force is required to change an object's velocity.
Which of the following changes when an unbalanced force acts on an object?
velocity
What will happen to a moving object that is not acted on by an unbalanced force?
It will not accelerate. That means that its velocity won't change.
How does the centripetal force cause an object to change in motion?
Any net force will change an object's velocity. In the case of a centripetal force, it changes the direction of the movement, and therefore its velocity.
When the velocity of an object changes it is acted upon what?
Force
What can cause the velocity of an object to change?
Acceleration is a change in the speed of an object (contrary to popular belief - acceleration ban be an increase or decrease in speed). Velocity of an object only changes when acted on by an external force like a push, friction or other force. Objects in motion stay in motion until acted on by an external force
What changes speed and direction?
Velocity is defined as a vector quantity representing both speed and direction. Acceleration is defined as the rate at which velocity changes. The acceleration of an object changes when it is acted upon by an unbalanced force.
If an object falls of a shelf how do you know a force as acted on it?
You know a force has acted on the object because the objects velocity has changed as the result of a force, f= mdv/dt.
What occurs when unbalance force are acting on an object?
An object will continue to travel at constant speed unless acted on by an unbalanced force, and for every force acted on there is an equal opposite reaction in the other way. So the speed and direction of the object will be changed.Source(s):F=MA
What Always change the velocity of an object?
Force changes the velocity of an object by acceleration, a=F/m.
What is something that changes motion in an object?
A force is required to change an object's velocity.
Which of the following changes when an unbalanced force acts on an object?
velocity
When does an object undergoes acceleration?
Acceleration is the change in velocity of an object over time. Take note that velocity is a vector quantity which means that it has magnitude and direction...Thus...An object undergoes acceleration when:1. there is a change in the magnitude of the velocity (speed) of an object.2. there is a change in direction of an object.3. it changes both in direction and magnitude.
What will happen to a moving object that is not acted on by an unbalanced force?
It will not accelerate. That means that its velocity won't change.
What is the net force on a falling object when it reaches terminal velocity?
An object falling at terminal velocity is moving at constant speed (that's what terminal velocity means) and we will assume it is not changing direction (i.e. it is falling straight down; in reality it is more likely to be bobbing and weaving on the wind.) Constant speed and direction is another way of saying constant velocity. when an object is acted upon by a net force, it's velocity changes. So, since we know that the velocity is not changing, there is no force.
What happen if an object is acted upon by balanced forces?
In this case, it is as if no force acted on the object. The object won't acceleration; if it is resting, it will continue resting, and if it is moving, it will continue moving at the same velocity.
