Carew 8.7A Acceleration-Newton's 2nd Law Notes

Open Ended

How does Newton's Second Law of Motion help us understand the relationship between force, mass, and acceleration in everyday life?

Open Ended

Which one does not belong? Why?

Multiple Select

Which of the following scenarios are examples of unbalanced forces? Select all that apply.

• A traffic light turns green. Driver steps on the gas pedal and car moves faster and faster.

• A car reaches a curve in the road, causing it to change direction.

• A traffic light turns red, and the car comes to a stop.

• A car is parked in a parking lot.

Multiple Choice

According to Newton's 1st Law, what will happen to an object at rest if no unbalanced force acts on it?

• It will start moving.

• It will stay at rest.

• It will accelerate.

• It will change direction.

Multiple Choice

Which statement best describes what unbalanced forces do to an object?

• They keep the object at rest.

• They cause the object to accelerate.

• They slow the object down to a stop.

• They have no effect on the object.

Multiple Choice

Which force is responsible for causing the apple to speed up as it falls from a tree?

• Friction

• Gravity

• Magnetism

• Electricity

Open Ended

Explain how unbalanced forces can affect the motion of an object, using examples from everyday life.

Multiple Choice

Is the apple accelerating?

• The apple is accelerating because forces are unbalanced

• The apple is not accelerating because forces are balanced

• The apple is deccelerating

• The apple is changing direction

Open Ended

Compare the acceleration of the apple at rest on the table and the apple falling due to gravity. What causes the difference?

Multiple Choice

Which of the following statements is true about the cyclist moving at a constant speed in a straight line?

• The cyclist is accelerating.

• The cyclist is not accelerating.

• The cyclist is decelerating.

• The cyclist is changing direction.

Which of the following are true about objects with less mass? Select all that apply.

• They are easier to accelerate.

• They are harder to accelerate.

• They speed up more easily.

• They slow down more easily.

Multiple Choice

According to Newton's 2nd Law, if the same amount of force is applied to objects of different masses, which object will have the greatest acceleration?

• The object with the least mass

• The object with the most mass

• All objects will have the same acceleration

• The object with the largest volume

Open Ended

Explain why a 2 kg box would experience greater acceleration than a 10 kg box when the same unbalanced force is applied to both.

Open Ended

Which box would experience the least acceleration when the same unbalanced force is applied: 2 kg, 5 kg, or 10 kg? Explain your reasoning.

Multiple Select

Which of the following statements correctly describe Newton's 2nd Law?

• Acceleration is directly proportional to the force applied.

• If you apply a greater force, the object accelerates more.

• Acceleration is inversely proportional to mass.

• Acceleration does not depend on the direction of force.

Multiple Choice

If you push a skateboard forward, in which direction will it accelerate?

• In the same direction as the force applied

• In the opposite direction of the force applied

• It will not accelerate

• It will move in a random direction

Multiple Select

Select all correct statements about the relationship between force, mass, and acceleration according to Newton's 2nd Law.

• Acceleration increases with increased force if mass is constant.

• Acceleration decreases with increased mass if force is constant.

• Force is equal to mass times acceleration.

• Acceleration is independent of mass.

Multiple Choice

Which of the following statements about Newton's 2nd Law is correct?

• Acceleration is directly proportional to force and inversely proportional to mass.

• Acceleration is inversely proportional to both force and mass.

• Acceleration is directly proportional to both force and mass.

• Acceleration is independent of force and mass.

How does Newton's Second Law of Motion help us understand the relationship between force, mass, and acceleration in everyday situations?

Multiple Choice

Which scenario does not involve a change in the motion of the car?

• A traffic light turns green. Driver steps on the gas pedal and car moves faster and faster.

• A car reaches a curve in the road, causing it to change direction.

• A traffic light turns red, and the car comes to a stop.

• A car is parked in a parking lot.
