Question

1. explain the difference between distance - time graphs and velocity - time graphs. what does the slope represent in each? 8. a passenger feels pushed backward when a car suddenly accelerates. which of newtons laws explains this, and why?

Explanation:

Question 7:

A distance - time graph shows the total distance traveled over time. Its slope represents speed (rate of change of distance with time). A velocity - time graph shows the velocity of an object over time. Its slope represents acceleration (rate of change of velocity with time).

Question 8:

Newton's first law, also known as the law of inertia, explains this. Inertia is the tendency of an object to resist changes in its state of motion. When the car accelerates, the passenger's body wants to stay in its original state of motion (at rest or moving at a slower speed), so it appears as if the passenger is pushed backward relative to the accelerating car.

Answer:

Question 7:

Distance - time graph: shows total distance, slope is speed. Velocity - time graph: shows velocity, slope is acceleration.

Question 8:

Newton's first law. Due to inertia, passenger's body resists change in motion.
