It doesn't. For example, you can go in a straight line, and speed up or slow down, without changing direction. And if there is both a change in direction and a change in speed, the change of speed wouldn't be the CAUSE for a change in direction. (On the other hand, both can be caused by a force applied to an object.)
What else can I help you with?
What changes can a force produce in the motion of an object?
it is speed of motion and direction of motion
Forces can change the what of movement of an object?
Forces can change the speed, direction, or both speed and direction of movement of an object.
What changes in motion can produce acceleration?
Changes in speed, changes in direction, and both combined can produce acceleration in an object's motion. Acceleration occurs when there is a net force acting on an object, causing it to speed up, slow down, or change direction.
When you know speed and direction what does that tell?
Speed and direction combined produce velocity, which is a vectory notation.
What term refers to any change in speed direction or both?
Acceleration refers to any change in speed, direction, or both. It can be either an increase or decrease in speed, a change in direction, or a combination of both.
How is acceleration related to the change in speed?
A change in speed (and/or direction) is acceleration.
When you change speed and direction you are changing what?
When you change speed and direction, you are changing your velocity. Velocity is a vector quantity that includes both speed and direction. So when you modify either speed, direction, or both, you are altering your velocity.
What is a change in velocity due to a in direction or speed?
A change in velocity due to a change in direction can occur when an object changes its direction of motion, even if its speed remains constant. A change in velocity due to a change in speed occurs when an object either accelerates or decelerates, resulting in a change in its speed.
Is a change in speed a change in velocity?
Yes, a change in speed can also be a change in velocity if the direction of the object's motion also changes. Velocity is a vector quantity that includes both speed and direction, so any change in speed or direction will result in a change in velocity.
What changes in motion can result in a change in velocity?
Any change in motion (direction or speed) is a change in velocity.Velocity is a vector quantity which means that it has a magnitude and a direction.
If an object is moving at a constant speed in one direction what is needed to change its speed or direction?
To change the speed or direction of an object moving at a constant speed, a force must be applied in the opposite direction of its motion to slow it down and a force must be applied in the desired direction of its new path to change its direction. The magnitude and direction of the force will determine how much the speed or direction changes.
A situation when you can accelerate but the cars' speed doesn't change?
"Acceleration" means a change of speed or direction. If the direction of your motion changes, then there is acceleration, even if your speed doesn't change.
