Carl wants to determine how the angle of a ramp affects the amount of force he must exert to lift a heavy antique toy car. He predicts that the steeper the angle of the ramp, the greater the force he will have to use to move the car up the ramp. He changes the ramp angle by using a different number of textbooks each trial. To collect his data, he uses a spring scale to measure his force and records his results onto a table. He was excited that his hypothesis proved to be correct!
The question Carl is investigating in this experiment is:
How will the size of the toy car affect how much force is required to lift it?
How will the angle of the ramp affect how much force is required to lift it
How will the surface of the ramp affect how much force is required to lift it?
Carl wants to determine how the angle of a ramp affects the amount of force he must exert to lift a heavy antique toy car. He predicts that the steeper the angle of the ramp, the greater the force he will have to use to move the car up the ramp. He changes the ramp angle by using a different number of textbooks each trial. To collect his data, he uses a spring scale to measure his force and records his results onto a table. He was excited that his hypothesis proved to be correct!
Carl's hypothesis should state:
If I increase the angle of the ramp, then more force will be required to lift the toy car.
If I decrease the angle of the ramp, then more force will be required to lift the toy car.
If I decrease the angle of the ramp, then the amount of force I have to exert will not change to lift the toy car.
