Angular momentum is conserved in the above examples such as the ice skater, the torque or the rotating effect of the force is almost equal to zero because there is negligible friction between the skates and the ice.

<h3>What is principle of conservation of angular momentum?</h3>

The principle of conservation of angular momentum states that the total angular momentum acting on an object is constant, provided there is no  external torque acting on the object.

Angular momentum of a system is conserved as long as there is no net external torque acting on the system.

<h3>Examples of conservation of angular momentum</h3>
  • the spinning ice skater
  • someone spinning in an office chair
  • a child spinning on roller coaster  

Thus, angular momentum is conserved in the above examples such as the ice skater, the torque or the rotating effect of the force is almost equal to zero because there is negligible friction between the skates and the ice.

The hockey player is moving at a speed of 9. 5 m/s. if it takes him 2 seconds to come to a stop under constant acceleration, how
Lunna [17]

Answer:

9.5\; {\rm m}.

Explanation:

Let u and v denote the velocity of this hockey player before and after stopping, respectively. The question states that u = 9.5\; {\rm m\cdot s^{-1}} and implies that v = 0\; {\rm m\cdot s^{-1} since the hockey player has come to a stop.

The duration of this acceleration is t = 2\; {\rm s}.  

Since the acceleration of this hockey player was constant, SUVAT equation would apply. In particular, the SUVAT equation x = (1/2)\, (v + u) \, (t) gives the displacement x of this hockey player during that 2\; {\rm s} of acceleration:

\begin{aligned} x &= \frac{1}{2}\, (9.5\; {\rm m\cdot s^{-1}} + 0\; {\rm m\cdot s^{-1}})\, (2\; {\rm s}) = 9.5\; {\rm m} \end{aligned}.

In other words, this hockey player would have travelled 9.5\; {\rm m} while stopping.

3 things that Gravity affects
slamgirl [31]

Answer: See explanation

Explanation:

Gravity is simply referred to as the force of attraction between two particles or masses. Through gravity, the moon moves round the Earth.

Gravity also causes a fruit to fall from its tree. It can also cause an object to roll and fall from the table to the ground. In gravity, distance and mass are vital.

A baseball leaves a bat with a horizontal velocity of 20 m/s. In a time of 0.25 s, How far will it have traveled horizontally?
Maurinko [17]

Distance traveled by the ball is given by

distance = speed \times time

here we know that

speed = 20 m/s

times = 0.25 s

now we have

distance = 20 \times 0.25

distance = 5 m

so ball will travel 5 m distance in the given interval of time
