An eighth-grade class is studying the motion of objects. They have learned the following concepts about motion.

Motion occurs when there is a change in the position of an object with respect to a reference point.

While the speed of the object may change at various times during a trip the average speed for the trip is found by dividing the total distance by the total time.

The motion of the object can be changed by varying the amount of net force acting on the object or by varying the mass of the object.

The teacher asked students to design investigations to determine how changing the forces acting on an object or the mass of the object would change its motion.

The materials for the investigation included:

1 - toy cart

3 - 10N weights

1 - pulley

2 - meters of string

One group of students decided to design an investigation to determine how different amounts of mass on the toy cart would affect the speed of the toy cart. They set up their investigation as shown below:



The students performed several trials using different masses in the toy cart (M1). They hung a mass shown as (M2) to pull the toy cart as it dropped.

Below is a table they made to record their results.





Which of the following would be a way to test the effect changing the amount of force acting on the object has on the average speed of the object?
Move the cart at various speeds and determine the force at M1
Add varying numbers of weights to M1 and measure the speed of the car.
Add varying numbers of weights to M2 and measure the speed of the cart.
Move the cart at various speeds and determine the force exerted by M2

Sagot :

Add varying numbers of weights to M1 and measure the speed of the car.

Add varying numbers of weights to M2 and measure the speed of the cart.

How to test the effect of weight on the speed of object?

In order to test the changing amount of force that is acting on the object has effect on the average speed of the object we have to change the amount of weight on the object and allows it to move to a certain point in this way we can check the effect of changing amount of weight on the speed of the object.
