1. How many g’s are you pulling?
# of g’s (or g force) – an object’s apparent weight ( the weight you “feel”)
– the number of times lighter or heavier an object feels
– the ratio of the normal force and the force of gravity (weight)
During free fall
Hence, you feel weightless!

2. How many g’s are you pulling?
# of g’s (or g force) – an object’s apparent weight ( the weight you “feel”)
– the number of times lighter or heavier an object feels
– the ratio of the normal force and the force of gravity (weight)
Sitting in a non-accelerating chair
Hence, you feel your normal weight!

3. How many g’s are you pulling?
Consider a cart accelerating down a frictionless incline.
Since is unbalanced it causes the cart to accelerate as it moves down the incline

4. How many g’s are you pulling?
Hence, you feel lighter since the normal force is less than your weight at any non-zero angle
(you are pulling less than 1g)!

5. How many g’s are you pulling?
Driving at constant speed through a circular valley
Since the object accelerates upward (inward)
But

6. How many g’s are you pulling?
Driving at constant speed through a circular valley
Since the object accelerates upward (inward)
Hence, you feel heavier since the normal force is greater than your weight (more than 1g)!
