There are two possibilities. One is that he is falling at a constant (positive) speed. In this case, the downward force of gravity is exactly offset by the upward force of drag or air resistance. The parachutist is said to have reached terminal velocity.
The second possibility is that he is moving downwards at a constant speed of zero. He has hit the ground! The parachutist may be said to have reached a terminal situation!
constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.
A body moving with constant speed in a circular path has acceleration changing at every point.
If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.
I wonder what is the constant speed of this moving car
No. Velocity combines speed and the direction of motion.Constant velocity is constant speed in a straight line.In circular motion, the velocity is always changing even if the speed is constant,because the direction is always changing.
The parachutist will no longer accelerate. They will just glide with constant velocity and enjoy the scenery.
The object that is moving at a constant speed will slow down. Its new velocity will be determined by the original constant speed along with the new combined mass of the moving object and the additional "large mass."
Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.
Yes. If an object is moving at a constant speed the average speed and the constant speed are the same.
A car moving at constant speed in a straight line is also moving at constant velocity.
None, as "not moving at all" is just moving at a constant speed of zero. Special relativity shows that there is nothing unique or different about zero speed. It is just a value of constant speed.
determine if the momentum of an object moving in a circular path at constant speed is constant.
determine if the momentum of an object moving in a circular path at constant speed is constant.
it means the object is moving at a constant speed
When the speed of an object remains the same - it does not increase or decrease - we say it is moving at a constant speed.
When both sides are pulling with equal force, the object is either moving at a constant speed or it is stationary (not moving) :)
if an object is moving without any net force or acceleration, it is moving at constant speed, or constant velocity. For example a satellite orbiting the earth is moving at constant speed, a car traveling at 60 mph, a wind of 20 mph. etc.
