NO NO NO
When another speed limit sign is reached that changes the limit from the previously posted one.
Yes, momentum changes when speed changes because momentum is directly proportional to an object's velocity. When an object's speed changes, its momentum will also change accordingly.
Velocity change can result in changes in an object's speed and/or direction of motion. This change in velocity can be caused by forces such as acceleration, deceleration, or changes in direction, which can affect the object's kinetic energy and momentum.
it changes the speed
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.
The speed limit doesn't change, but you are expected to make a reasonable adjustment to your speed to compensate for the conditions. So basically, as fast as you can go at or below the speed limit without getting into a wreck.
velocity. When an object changes direction, its velocity vector changes, even if the object's speed remains constant. This change in velocity can be caused by forces such as gravity or friction acting on the object.
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.
In the 1970's the speed limit was lowered as a national recommendation in the belief that the higher speeds caused excess gasoline consumption.
A change in an object's state of motion is caused by the application of an external force acting on the object. This force can be in the form of a push, pull, or any other interaction that changes the object's speed or direction of motion.
velocity
A parameter is a limit: could be a speed limit on the road. A variable is something that changes in the system: could be the actual speed of a car.
