Answer:

<em>relative</em><em> </em><em>motion </em><em>is </em><em>the </em><em>motion</em><em> </em><em>of </em><em>an </em><em>object</em><em> </em><em>compared </em><em>to </em><em>that </em><em>of </em><em>another </em><em>object.</em><em>f</em><em>o</em><em>r</em><em> </em><em>example</em><em> </em><em>two </em><em>cars </em><em>driving</em><em> </em><em>in </em><em>the </em><em>same </em><em>highway </em><em>in </em><em>the </em><em>same </em><em>direction</em><em>.</em>

<em>I </em><em>hope</em><em> this</em><em> helps</em>

Relative motion means a motion relative to a reference point. We can also say, relative motion means motion referred or observed from a reference point.

For example, Alex is in a train and Ace is at the station, when the train starts moving, for Ace it is moving at a speed of 10 m/s, but for Alex it is moving at 0 m/s, or we can say that it is at rest for Alex, but in motion for Ace. This is relative motion.

A rubber ball and a lump of clay have equal mass. They are thrown with equal speed against a wall. The ball bounces back with ne
gregori [183]

Answer:

The ball experiences the greater momentum change

Explanation:

The momentum change of each object is given by:

\Delta p = m \Delta v= m (v-u)

where

m is the mass of the object

v is the final velocity

u is the initial velocity

Both objects have same mass m and same initial velocity u. So we have:

- For the ball, the final velocity is

v=-u

Since it bounces back (so, opposite direction --> negative sign) with same speed (so, the magnitude of the final velocity is still u). So the change in momentum is

\Delta p=m(v-u)=m((-u)-u)=-2mu

- For the clay, the final velocity is

v=0

since it sticks to the wall. So, the change in momentum is

\Delta p = m(v-u)=m(0-u)=-mu

So we see that the greater momentum change (in magnitude) is experienced by the ball.
