CP Ch02.7 Free Fall

What concept did Galileo develop to study falling objects?

• Velocity

• Acceleration

• Friction

• Gravity

According to the text, what does the acceleration of falling objects depend on?

• Time

• Height

• Mass

• Shape

What is weight defined as?

• Mass divided by acceleration

• Mass multiplied by acceleration

• Mass plus acceleration

• Mass minus acceleration

What does Newton's second law relate to?

• Velocity, time, and distance

• Force, mass, and acceleration

• Temperature, pressure, and volume

• Energy, power, and work

What did Galileo's experiments disprove regarding falling objects?

• Lighter objects fall faster

• Heavier objects fall slower

• Heavier objects fall faster

• Objects of different weights fall at the same rate

What is the relationship between weight and mass for freely falling objects?

• They are different for each object

• They are inversely proportional

• They are directly proportional

• They are the same

What equation did Isaac Newton use to connect force, acceleration, and inertia?

• a = F/m

• F = ma

• m = F/a

• a = m/F
