What else can I help you with?
Can velocity of a body vary if speed of the body change?
velocity means speed of an object and in a definite direction.That shows velocity changes with speed
How is speed of a body related its velocity?
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.
How is the speed of a body related to its velocity?
The speed is the MAGNITUDE of the velocity, i.e., without regard to the direction.
When does a body has uniform speed?
A body has uniform speed if it covers equal distances in equal intervals of time however short the interval may be.
Can a body have nonzero average speed but have zero average velocity give example?
Yes, a body can have a nonzero average speed but zero average velocity if it moves around a closed path and returns to its starting point. For example, if a car travels around a circular track at a constant speed, its average speed will be nonzero (as distance is covered), but its average velocity over the entire trip will be zero as the displacement is zero.
What heavenly body does the earth travel round?
The Earth travels around the Sun.
What is the speed velocity of a body?
In common speech, velocity means speed, they are the same thing.
What is the speed and direction of a moving body called?
The speed and direction of a moving body is called velocity. Velocity is a vector quantity that specifies both the speed of an object and the direction in which it is moving.
Can a body have a constant velocity but varying speed?
No. If the speed varies, the body accelerates, and velocity cannot be constant.
When do the velocity and speed of a moving body become equal?
The velocity and speed of a moving body become equal when the motion is along a straight line with no change in direction. In such cases, the velocity and speed have the same magnitude.
Can a velocity of a body change its speed is constant?
No. A body with constant velocity is either stationary or going at constant speed in a constant direction. The usual interpretation of speed and velocity goes like this. A velocity is a vector with magnitude and direction. The magnitude is usually called its speed. Changing a speed must change the length of the vector and changing the length of the velocity vector has to change the velocity.
A car traveling at a velocity of 45 mph crashed into a brick wall What is the velocity of the driver the moment after impact if the driver was wearing his seatbelt?
I saw this on that Myth show. The body travels the same speed of the car which would be 45mph.
