according to newton's first law, an object maintains its state of rest or motion unless acted upon by an external force. So a force is required to stop an object at rest and a force is also required to move an object at rest.
when the hockey player send a hockey puck flying across the ice , frictional force from the ice surface acts on the puck in opposite direction of the motion of puck to slow it down and stops it finally.
It is a well known fact that the ocean modifies the climate favorably so as to keep the ambient temperature warmer than it usually is inland away from the ocean so that is why the nightime drop in temperature will be less near the sea than inland.
Answer
input, output, processing and storage
Explanation:
<span>Velocity is a vector quantity, that's formally defined as the rate of change of position or displacement with time. When stating any vector like the velocity of an object, we talk about direction, as well as magnitude. That's why speed and velocity are different things. Speed is a scalar (a pure number, specified by magnitude, without direction), while velocity is a vector. To put it simply, speed is the magnitude of the velocity. When talking about velocity, we specify it according to some fixed frame of reference and its unit is meters/second. It can be measured in two ways. One is in the form of average velocity, while the other is instantaneous velocity. The formula for the former is as follows.</span>
