What's the Formula?
Random
100

This force acts on every object and always acts directly down from the center of mass of an object.

Force Gravity

100

What is formula for Force?

F = ma

If an elevator is in free fall what is the Force Normal felt by the person inside the elevator?

 0 N 

200

This force acts in the direction of motion

Force push/pull

200

What is the formula for Force Gravity?

F = mg   g=9.81m/s2

200

A scale on an elevator reads 750 N. At some point the scale reads 800 N. What is the motion of the elevator?

Upwards

300

This force acts in the opposite direction of motion

Force Friction

300

What is the formula for Force on an elevator?

F = m (a+g)

300

A scale reads 750 N on an elevator. At some point the scale reads 550 N. What is the direction of the elevator?

Downwards

400

When on a rollercoaster loop de loop, at the very top of the loop. What two forces act on you?

Force Normal and Force Gravity

400

Using the formula for force on an elevator, give me how the formula to solve for acceleration of an elevator

a = (FN / m ) - g


400

An elevator accelerates at 5 m/s2 and a man stands on a scale that reads 250 N. What is the mass of the man?

50 kg

F= ma       m = F / a   m= 250/5

500

This force always acts directly perpendicular to a surface

Force Normal

500

Using the formula for Force Normal, if you are given mass and force, which formula will you use for finding acceleration?

a = F / m

500

A 50kg man gets in an elevator and feels a force of 300 N acting on him. What is the acceleration of the elevator?

6 m/s2

F = ma     a = F/m     a= 300/50 = 6
