5 Force Inclines

Students pulled the same mass up an inclined plane that was 20 cm, 30 cm, and 40 cm long. Each time, they used a spring scale to measure the force needed to pull the mass up the inclined plane. What did they conclude?

• Less force was needed on the 20 cm plane
• More force was needed on the 40 cm inclined plane.
• The least amount of force was needed on the 40 cm inclined plane.
• The least amount of force was needed on the 30 cm inclined plane.

Is a waterslide an inclined plane?

• Yes

• No

The longer the inclined plane, the ___________________ to move the object

• the less input force you need
• the more input force you need
• the more output force you need
• the less output force you need

How does distance change the effort when using an inclined plane?

• as distance increases, effort decreases

• as distance decreases, effort decreases

• as distance increases, effort increases

• nothing, they both stay the same

If I want to use the least amount of force neccessary, I would need a 

• long, steep ramp
• short, gentle ramp
• long, gentle ramp
• short, steep ramp
