Question

newton’s second law of motion states: the ______ of an object depends on two variables: the ____ acting upon it and its ___.

ii. unbalanced forces and motion

1. when forces are ________, an object’s motion changes.
2. an object can:

• speed ________
• slow ________
• change ________

1. the acceleration happens in the same ________ as the force pushing or pulling the object.

iii. relationship between force, mass, and acceleration

1. more force applied = ________ acceleration
2. more mass = ________ acceleration
3. heavier objects need ________ force to move as fast as lighter objects.

Explanation:

Step1: Fill Newton's 2nd Law blanks

Newton's Second Law states: "The acceleration of an object depends on two variables: the net force acting upon it and its mass."

Step2: Fill Unbalanced Forces blanks

1. When forces are unbalanced, an object's motion changes.
2. An object can:

• Speed up
• Slow down
• Change direction

1. The acceleration happens in the same direction as the force pushing or pulling the object.

Step3: Fill Force-Mass-Acceleration blanks

1. More force applied = greater acceleration
2. More mass = less acceleration
3. Heavier objects need more force to move as fast as lighter objects.

Answer:

Newton's Second Law of Motion:

The acceleration of an object depends on two variables: the net force acting upon it and its mass.

II. Unbalanced Forces and Motion

1. When forces are unbalanced, an object's motion changes.
2. An object can:

• Speed up
• Slow down
• Change direction

1. The acceleration happens in the same direction as the force pushing or pulling the object.

III. Relationship Between Force, Mass, and Acceleration

1. More force applied = greater acceleration
2. More mass = less acceleration
3. Heavier objects need more force to move as fast as lighter objects.
