Which argument can be made using the data in the table?

• An object with more mass requires less force to move it.

• An object with more mass requires more force to move it.

• An object with more mass will accelerate less than objects with less mass.

• An object with more mass will accelerate more than objects with less mass.

A student is investigating acceleration using objects with different masses. She claims that mass affects the acceleration of objects when the force remains constant. The student creates a graph to represent the findings of her investigation. Which argument BEST supports the student's claim?

• As mass decreases, the acceleration of an object decreases because less force is required.

• As mass increases, the acceleration of an object increases because less force is required.

• As mass increases, the acceleration of an object decreases because more force is required.

• As mass decreases, the acceleration of an object increases because more force is required.

The diagram shows two boxes with the same force being applied to them. In the diagram, force (F) is shown in newtons (N), acceleration (a) is shown in meters/second (m/s ), and the mass is shown in grams (g). Which statement is supported by the diagram?

• The acceleration of an object is determined only by the mass of the object and not the force that is applied to it.

• The acceleration of an object is determined only by the force that is applied to it and not the mass of the object.

• Objects with a larger mass accelerate faster than objects with a smaller mass when the same force is applied.

• Objects with a larger mass accelerate more slowly than objects with a smaller mass when the same force is applied.

A student is investigating acceleration using balls with different masses. The student pushes each ball on a flat surface and records its acceleration. The table shows his observations. Which claim can the student make using his observations?

• A ball with a mass of 5 kg will have an acceleration that is less than 3.3 m/s when pushed with a force of 50 N.

• A ball with a mass of 10 kg will have an acceleration that is greater than 2.5 m/s when pushed with a force of 50 N.

• A ball with a mass of 25 kg will have an acceleration that is less than 1.7 m/s when pushed with a force of 50 N.

• A ball with a mass of 40 kg will have an acceleration that is greater than 1.4 m/s when pushed with a force of 50 N.

Match the following Law of motion with the correct example

• Hit a ball with 2 different forces, the ball will have greater acceleration due to larger force

• Newton's 1st law of motion

• Roll a ball across smooth/rough surfaces. The ball rolls faster on smooth because less fiction

• Newton's 3rd of motion

• Bouncing the ball on the court is the action, the floor pushing the ball back up is the reaction

• Newton's 2nd law of motion

A cart is pushed with different forces, and its acceleration is recorded. Analyze the data in the table to determine the relationship between force, mass, and acceleration. What can you conclude from the table?

• Increasing force increases acceleration regardless of mass.

• The acceleration depends only on the mass of the object.

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

• Acceleration remains constant regardless of changes in force.

A scientist pushes three objects with the same force of 15 N. Their accelerations are measured and recorded in the chart. Which statement best evaluates the evidence in the table to support Newton’s Second Law?

• Acceleration is not affected by the force applied or the mass of the object.

• The data supports the claim that force and mass determine acceleration.

• Mass increases the acceleration, disproving Newton’s Second Law.

• The scientist must have applied different forces to achieve these results.

Which statement best describes the relationship shown in the graph?

• • Force and acceleration are inversely proportional.

• The object’s acceleration is independent of the applied force.

• Doubling the force results in doubling the acceleration for this object.

• The object’s mass changes as more force is applied.

You observe two blocks with different masses being pushed with the same force. Analyze the table below, then construct an argument for how Newton’s Second Law explains the results.

• Acceleration decreases when the mass of the object increases because force is constant.

• Force and mass are directly proportional, causing acceleration to decrease as mass increases.

• Newton’s Second Law states that F = ma, so an increase in mass will result in a proportional decrease in acceleration if force remains constant.

• An object with greater mass resists motion entirely, regardless of applied force.
