Part of every velocity is a speed. Speed is the size of the velocity.But the velocity also has a direction, which the speed doesn't.'30 mph North' and '30 mph West' are the same speed but different velocity.
No, an object cannot have constant velocity and variable speed. Velocity is a vector quantity that includes both speed and direction. If the object's velocity is constant, then its speed must also be constant.
No, a particle cannot have zero speed and non-zero velocity simultaneously. Speed is the magnitude of velocity and if speed is zero, then velocity must also be zero.
The speed of an object plus its direction is called velocity. Velocity is a vector quantity that combines the object's speed (magnitude of the velocity) and its direction of motion.
Velocity measures the speed of an object in a specific direction. Unlike speed, velocity is a vector quantity that takes into account both the object's speed and the direction it is moving.
Speed in a given direction is velocity.
SPEED has the speed only; while VELOCITY has the direction and the speed.
Part of every velocity is a speed. Speed is the size of the velocity.But the velocity also has a direction, which the speed doesn't.'30 mph North' and '30 mph West' are the same speed but different velocity.
Speed in a given direction is called velocity.
Velocity is speed and direction
Velocity is speed with a direction
It is the speed or velocity at a particular instant.
Speed is a scalar, velocity is a vector. In other words, when the direction of the speed is relevant, it is called a velocity.
the object's 'velocity'
Velocity is the vector form of speed. It is the speed of an object in a specified direction.
Velocity is a vector, which means it has a direction, but speed isn't. Speed is the absolute value of velocity. Velocity can be negative, meaning that the speed is opposite to the direction that you're calling the positive direction.
Velocity describes both the speed and direction an object is moving.
