What changes if somethings speed or direction changes?
If an object's speed changes, it means that it is either speeding up or slowing down. If an object's direction changes, its velocity changes as well, as velocity is a vector quantity that includes both speed and direction. These changes in speed and direction are typically caused by forces acting on the object.
How can velocity change without changing the speed?
Velocity can change without changing speed when the direction of motion changes. Velocity is a vector quantity that includes both speed and direction, so if the direction changes while the speed remains constant, the velocity will change. This could happen if an object moves in a circle or changes direction on a curved path.
Why at a constant speed if an object changes its direction it is considered to be acceleration?
Acceleration is defined as any change in velocity, which includes changes in speed, direction, or both. When an object changes its direction while moving at a constant speed, it is still accelerating because its velocity is changing due to the change in direction. This change in velocity, even if the speed remains constant, is what defines it as acceleration.
Can you have constant speed but change in velocity?
Yes, you can have constant speed but change in velocity if the direction of motion changes. Velocity is a vector quantity that includes both speed and direction. So, even if the speed remains constant, if the direction changes, the velocity changes.
Does the speed of an object change when the speed changes?
Yes. The velocity changes when the direction of motion changes, because the definition of 'velocity' is 'speed and the direction'. If either speed or direction changes, then we say the velocity has changed. Notice that if the direction changes, then the velocity changes even if the speed doesn't. "Velocity" is not just a bigger word that you use for 'speed' when you want to sound smart. They mean different things.

What is the deffinition of acceleration?
The rate at which speed changes, and the direction in which it changes.

What happens to speed and velocity when a car turns but maintains the same speed?
When a car turns but maintains the same speed, the velocity of the car changes because velocity includes both speed and direction. The speed of the car stays the same, but the direction of the velocity changes as the car turns.
What changes when speed changes direction of motion changes or both factors change?
velocity
Is it true or false that acceleration can only occur when the speed of an object changes?
False. Acceleration is a measure of how quickly an object's velocity is changing, which includes changes in speed, direction, or both. So, acceleration can occur even if the speed of an object remains constant but its direction changes.
What changes in motion can result in a changes 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.
What are two types of accleration?
Changes in speed or direction
What changes a objects speed and motion and direction?
A force.
