Question

Give reasons for the following
1. Pushing a car is easier than pushing a truck .
2. Why does a fall on a hard surface hurt more than a fall on a sandy surface ?
3. Why does a fielder pull his arms back while trying to stop/catch a cricket ball ?
4. Why cars are provided with seat belts ?
5. How does a karate player break a pile of tiles or a slab of ice in a single blow .



please answer this it is very important
if you answer it I will follow u,thank all your answers and mark as brainliest

And no scamming please ​

Answer 1

Question 1:

• Pushing a car is easier than pushing a truck because the car has much lesser mass and weight as compared to that of a truck.

• Due to higher weight , the truck experience is more friction and is difficult to push.

Question 2:

• Falling on hard surface hurts more as compared to you falling on a sandy surface because :

• When we fall on hard surface the change in momentum of a body is very fast and hence we experience a higher force. This causes more pain.

• But , on a sandy surface the change in momentum of the body is much slower and hence we experience lesser force.

Question 3:

• Fielder pull back the arm a little bit while catching a cricket ball so as to decrease the rate of change of momentum of the ball.

• This would decrease the force exerted by the cricket ball on the hand.

• Hence , the fielder would not get hurt while catching the ball.

Question 4:

• Cars are provided with seat belts as safety devices.

• If the car suddenly stops due to inertia of motion the passengers have a tendency to move forward and might hit the dashboard of the car.

• Seat belts prevent this forward motion during sudden stopping of the car and hence prevents accident of the passengers.

Question 5:

• Karate players are able to break a whole pile of brick at one blow because they exert a huge momentum on the the pile of brick.

• The rate of change of momentum of the hand is very high resulting in generation of a high force.

• This high force can break the whole pile of bricks.

Pushing a car is easier than pushing a truck because the truck is much more heavier in comparison to the car due to which truck will experience high inertia.

Fielder pull back the arm a little bit while catching a cricket ball so as to decrease the rate of change of momentum of the ball.

This would decrease the force exerted by the cricket ball on the hand.

Hence , the fielder would not get hurt while catching the ball.

Cars are provided with seat belts as safety devices.

If the car suddenly stops due to inertia of motion the passengers have a tendency to move forward and might hit the dashboard of the car.

Seat belts prevent this forward motion during sudden stopping of the car and hence prevents accident of the passengers.

Karate players are able to break a whole pile of brick at one blow because they exert a huge momentum on the the pile of brick.

The rate of change of momentum of the hand is very high resulting in generation of a high force.

This high force can break the whole pile of bricks.
