According to Newton's first law, an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. It is the natural tendency of objects to keep on doing what they're doing. All objects resist changes in their state of motion. In the absence of an unbalanced force, an object in motion will maintain its state of motion. This is often called the law of inertia.

Your body would probably be forced forwards during the crash and to prevent injury the air bags would deploy making sure you dont fly out the car window.

Answer:

• Bring another magnet wound with a copper wire, at the top of the fixed magnet. Here EMF will be generated by mutual induction

Define average velocity and instantaneous velocity when are they same

Vlada [557]

Answer:

Look to the explanation

Explanation:

Average velocity: is the average rate of change of displacement with

respect to time

Average velocity is a measure for distance traveled in a given time

We can calculate the average velocity by the rule $v=\frac{s}{t}$

where s is the displacement and t is the time

Instantaneous velocity: is the velocity of an object in motion at a

specific point (x , t)

instantaneous velocity is the limit of velocity as the change in time

approaches zero

We can calculate the instantaneous velocity by the rule $v=\frac{ds}{dt}$

Average velocity is equal to the instantaneous velocity when

acceleration is zero
