Question

both observations are correct because motion depends on the observer.\different observers can describe the same objects motion differently depending on whether they are moving or standing still.\although the forces acting on an object do not change...\scientists and engineers must consider frames of reference...\3. why does the rider on the skateboard feel like they are being pulled forward when the skateboard stops? 5 pointsa forward force suddenly increasesgravity pulls harder on the riderthe riders body continues moving due to inertiaair resistance pushes the rider forward4. part a: 5 pointshow does the observer standing still describe the riders motion after the skateboard stops?a forward force acts on the riderthe rider stops immediatelythe rider continues moving forward due to inertiagravity causes the rider to fall forward

Explanation:

For question 3: This is explained by Newton's first law of motion (inertia), which states that an object in motion tends to stay in motion unless acted on by an unbalanced force. When the skateboard stops, the rider's body continues moving forward.
For question 4 Part A: A stationary observer will see the rider's body keep moving forward after the skateboard stops, as inertia maintains the rider's forward motion until another force stops them.

Answer:

1. The rider's body continues moving due to inertia
2. Part A: The rider continues moving forward due to inertia
