Sistemas de referencia y MRU

The video tutorial explores the concepts of motion, reference systems, and how our perception of movement changes based on our frame of reference. It delves into the definitions of position, trajectory, displacement, and distance, highlighting the differences between them. The tutorial also explains speed and velocity, including average and instantaneous speed, and introduces acceleration, discussing how it is measured and its role in motion.

How does the perception of motion change when you are inside a moving vehicle?

• Objects inside appear to move.

• Objects outside appear to move.

• Objects inside appear to move faster.

• Objects outside appear stationary.

What is a reference system used for in the context of motion?

• To define a coordinate origin for measuring distances.

• To measure the speed of an object.

• To determine the weight of an object.

• To calculate the time taken for a journey.

What remains constant regardless of the path taken between two points?

• The trajectory.

• The distance traveled.

• The displacement.

• The time taken.

How is speed defined in the context of motion?

• As the change in velocity over time.

• As the time taken to travel a distance.

• As the distance traveled divided by the time taken.

• As the acceleration of an object.

What is the difference between instantaneous speed and average speed?

• Instantaneous speed is constant, average speed varies.

• Instantaneous speed is measured at a specific moment, average speed is over a journey.

• Instantaneous speed is always higher than average speed.

• Instantaneous speed is measured in kilometers, average speed in meters.

What does acceleration measure in terms of motion?

• The total distance traveled.

• The change in speed over time.

• The time taken to stop.

• The direction of motion.

In what unit is acceleration typically measured?

• Meters per second.

• Kilometers per hour.

• Meters per second squared.

• Seconds per meter.
