Due 10/2: 8.7A/B Lab Practical Review

A student hangs bananas on a spring scale. The pointer stops at 5 N.
What does the reading on the spring scale represent?

• The mass of the block

• The gravitational force (weight) on the block

• The volume of the block

• The friction acting on the block

A student hangs a small object on the spring scale.
The pointer on the mass side shows 200 g.
What does this value represent?

• The weight of the object in newtons

• The mass of the object in grams

• The force of friction acting on the object

• The spring’s stretch in centimeters

A 10-kg box is pushed to the right with 25 N and pulled to the left with 5 N.

Find the acceleration of the box. JUST WRITE THE NUMBER!2

What is the unit for acceleration?

• 
• 
• 

If a 100 kg object is accelerating towards earth at 9.8m/s^2 what is the force pulling it down. Just write the number and round to the nearest hundredth!

In the penny–index card–cup setup, a quick horizontal flick of the card causes the penny to drop straight into the cup because its inertia resists horizontal motion.

• True

• False

• Banana

• Hi!

Ishan sits on a low-friction rolling chair facing a lab wall. He pushes the wall with his hands and rolls backward. Which pair best represents the action–reaction forces?

• Ishan pushes the wall; Ishan moves backward
  

• Ishan pushes the wall; the wall pushes Ishan

• Ishan pushes the wall; the floor pushes the wall

• The wall pushes Ishan; gravity pulls Ishan
