Motion detector graphs, distance vs time

In summary, the conversation discussed the behavior of a ball and a car when dropped or parked on a steep hill. The graph of their distance-time relationship would be curved, with the speed increasing as time progresses. A straight upwards sloping graph would not accurately represent their motion.

hi!
a ball is dropped from a height of 1 meter above the floor. Take the origin to be the point from which the ball is released.
would the graph be like a curved graph rising to the right starting from the origin?

how would the graph look like if a car is parked on a steep hill?

thank you

As time progresses the downwards speed of the ball (and the car) increases. If the speed of an object increases it covers more distance in the same time. This implies that the object covers more distance in the same time interval at a later time in its motion. How should the distance - time graph have to look then? Will a straight upwards sloping graph do?

for your question. Based on the information provided, the motion detector graph for the ball being dropped from a height of 1 meter would indeed show a curved graph rising to the right. This is because as the ball falls, its distance from the origin increases at a faster rate over time due to the acceleration of gravity.

In the case of a car parked on a steep hill, the motion detector graph would depend on the orientation of the hill and the direction of the car's motion. If the car is parked on a hill with a steep incline, the graph would likely show a steep incline as well, indicating a rapid increase in distance from the origin. However, if the car is parked on a hill with a gentle incline, the graph may show a more gradual increase in distance. If the car is parked on a hill with a downward slope, the graph would show a decrease in distance over time as the car moves away from the origin. Ultimately, the shape of the graph would depend on the specific details of the hill and the car's position and motion.
 

1. What is a motion detector graph and how is it used?

A motion detector graph is a visual representation of the movement of an object over time. It plots the distance traveled by the object on the y-axis against time on the x-axis. This type of graph is commonly used in physics experiments to analyze the motion of objects and determine their speed, velocity, and acceleration.

2. How do you interpret a distance vs time graph?

A distance vs time graph shows how the position of an object changes over time. The slope of the graph indicates the object's speed or velocity. A steeper slope indicates a greater speed, while a flatter slope indicates a slower speed. The distance traveled can also be calculated by finding the area under the graph.

3. What are the different types of motion shown on a distance vs time graph?

There are three types of motion that can be shown on a distance vs time graph: constant speed, uniform acceleration, and non-uniform acceleration. Constant speed is represented by a straight, diagonal line, uniform acceleration is shown by a curved line, and non-uniform acceleration is shown by a curved line that changes direction.

4. How can a motion detector graph be used to determine the acceleration of an object?

The acceleration of an object can be determined by analyzing the slope of a distance vs time graph. If the slope is constant, the object is moving with a constant speed and has no acceleration. If the slope is increasing, the object is accelerating at a constant rate. If the slope is changing, the object has non-uniform acceleration.

5. Can a distance vs time graph show negative values?

Yes, a distance vs time graph can show negative values. This typically occurs when an object is moving in the opposite direction of the positive direction on the graph. The negative values show the distance traveled in the opposite direction from the starting point.
