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:

For question 7: A distance - time graph shows the distance an object has traveled over time. The slope represents the speed of the object. A velocity - time graph shows the velocity of an object over time, and the slope represents the acceleration of the object.
For question 8: Newton's First Law (Law of Inertia) explains this. The passenger's body has inertia and wants to stay in its original state of motion. When the car accelerates forward, the passenger's body resists the change in motion and appears to be pushed backward relative to the car.

Answer:

1. Distance - time graph: shows distance over time, slope is speed. Velocity - time graph: shows velocity over time, slope is acceleration.
2. Newton's First Law (Law of Inertia). Passenger's body resists change in motion due to inertia.
