Question

Q1. A truck driver places a create on his perfectory slick flatbed, but forgets to secure it to the truck.   As he drives off, the crate slides and falls off the back. Explain why this occurred in terms of Newton's first law.

Q2. Describe what happens if you are riding on a skateboard and hit a curb with the front wheels using Newton's first law.

Q3. Imagine an air puck with a limitless air supply-i.e a level air table of infinite length,

     a. Once pushed, would the air puck continue to travel forever?

     b. Why or why not?

Q4. List three example of Newton's first law in action in everyday life.

Q5. A heavy mass box and a light mass box are accelerated over the same distance using the same force. Ignoring friction, which mass will require more force to bring it to a stop?

Q6. Describe two examples of Newton's third law in action in real life.   Except for balloon rockets.

Q7. About an air balloon rockets,

        a. Why does the balloon move when it is blown up and the pressure inside the balloon is released?

        b. Why is the air pushed out of the balloon? In other words, what is pushing it ?

        c. List some suggestion that might improve the performance of the balloon rocket. (Hint: think of what actual rockets look like / have)

Explanation / Answer

question 2:

1 st Law Your body will keep moving forward and fly off your skateboard since the curb only stops the board, not yourself.

question 4:

a) When a blanket is given a sudden jerk, the dust particles in it fall off due to inertia at rest.

b) Consider a coin placed on the plate covering a tumbler. If the plate is sudden flicked off, the coin falls into the tumbler due to inertia of rest.

c)  When a person jumps out of a moving vehicle, he falls forward due to inertia of motion

question 6:

a) A duster placed on a table continues to be at rest unless somebody displaces or lifts it by applying a force.
b) A football lying on the ground continues to be in the same position unless somebody kicks it with a force

question 5:

A heavy mass box and a light mass box are accelerated over the same distance using the same force.

heavy mass accelerated with more momentum than the light mass object . so we need more force to bring it at rest in case of heavy mass object
