Lab: Newton's Second Law

Question 1

Write a hypothesis about how the force applied to a cart affects the acceleration of the cart. Use the "if . . . then . . .because . . .” format and be sure to answer the lesson question: "How do force and mass affect the acceleration of an object?”

Write a hypothesis about how the force applied to a cart affects the acceleration of the cart. Use the "if . . . then . . .because . . .” format and be sure to answer the lesson question: "How do force and mass affect the acceleration of an object?”

Question 2

What did you include in your hypothesis? Check all that apply.

Revolt · Accepted Answer

The “if” part of the hypothesis refers to the force applied to the cart.; The “then” part of the hypothesis refers to a change in the acceleration.; The “because” part of the hypothesis describes the relationship between force and acceleration as a direct relationship given by Newton’s second law.

Question 3

✔ independentX dependentconstant

Revolt · Accepted Answer

✔ independent; The force applied to the physics cart is manipulated. This is the variable.: independent; The cart accelerates due to the force applied to the cart. Acceleration is therefore the variable.: dependent; A “constant” is a parameter that stays the same regardless of the variables. One parameter of the cart that is held constant is the .: mass

Revolt · Accepted Answer

✔ independent; The mass of the physics cart is manipulated. This is the variable.: independent; The cart accelerates differently as the mass of the cart changes. Acceleration is therefore the variable.: dependent; A “constant” is a parameter that stays the same regardless of the variables. One parameter that is held constant is the .: applied force

Question 9

Write a hypothesis about how the mass of a cart affects the acceleration of the cart. Use the "if . . . then . . . because . . .” format and be sure to answer the lesson question: "How do force and mass affect the acceleration of an object?”

Revolt · Accepted Answer

If the mass of a cart increases, then the acceleration of the cart decreases when the force applied to the cart is held constant, because mass and acceleration are inversely proportional to each other according to Newton's second law.
