Newton's 2nd Law Digital Formative Assessment

What is the formula for Newton’s Second Law of Motion? (DOK Level 1)

• F = m + a

• F = m * a

• F = m / a

• F = a / m

If a 10 kg object is accelerating at 5 m/s², what is the force acting on it? (DOK Level 2)

• 50 N

• 5 N

• 15 N

• 100 N

If two objects with different masses experience the same force, what will happen to their accelerations? (DOK Level 2)

• The object with greater mass will accelerate more

• The object with less mass will accelerate more

• Both will accelerate equally

• Neither will accelerate

A car requires 2000 N of force to accelerate at 2 m/s². What is its mass? (DOK Level 3)

• 1000 kg

• 500 kg

• 2000 kg

• 4000 kg

How does an increase in mass affect acceleration if the applied force remains constant? (DOK Level 3)

• Acceleration increases

• Acceleration decreases

• Acceleration remains the same

Why does a loaded truck take longer to accelerate than an empty one when the same force is applied? (DOK Level 3)

• The truck’s mass increases, reducing acceleration

• The truck’s friction decreases

• The truck’s engine power increases

• The truck’s weight does not affect acceleration

Design an experiment to test the relationship between force and acceleration. (DOK Level 4)

• Describe materials and procedures

• List variables to be measured

• Predict expected outcomes

• All of the above

Which scenario best illustrates Newton’s Second Law? (DOK Level 2)

• A stationary object remaining at rest

• A person pushing a shopping cart, causing it to accelerate

• A ball rolling indefinitely on a frictionless surface

• A satellite orbiting Earth

If a 20 kg object experiences a force of 40 N, what is its acceleration? (DOK Level 3)

• 2 m/s²

• 20 m/s²

• 40 m/s²

• 0.5 m/s²

Imagine a futuristic vehicle that can adjust its mass instantly. How would you design an experiment to test the relationship between force, mass, and acceleration? (DOK Level 4)

• By using a vehicle with adjustable mass and measuring acceleration for different forces applied.

• By using a vehicle with constant mass and measuring acceleration for different forces applied.

• By using a vehicle with adjustable mass and measuring force for different accelerations achieved.

• By using a vehicle with constant mass and measuring force for different accelerations achieved.
