Forces and Motion Concepts

In this lesson, Kaylee introduces Newton's Second Law, emphasizing the relationship between force, mass, and acceleration. The lesson begins with a recap of Newton's First Law, explaining how unbalanced forces affect motion. Through practical examples, Kaylee demonstrates how different forces and masses influence acceleration. The lesson concludes with an interactive game that allows students to experiment with these concepts, reinforcing their understanding of how force and mass affect acceleration.

What does Newton's First Law state about objects in motion?

• They change direction frequently.

• They require constant force to keep moving.

• They will eventually stop on their own.

• They stay in motion unless acted upon by an unbalanced force.

How is acceleration defined in terms of velocity?

• As a change in velocity.

• As a measure of distance.

• As a constant speed.

• As a decrease in speed.

What is the formula for Newton's Second Law?

• F = a / m

• F = ma

• F = m / a

• F = m + a

If two carts have the same mass but different forces applied, what will differ?

• Their shape.

• Their mass.

• Their acceleration.

• Their color.

When the same force is applied to two objects with different masses, which will accelerate faster?

• Neither will accelerate.

• Both will accelerate equally.

• The heavier object.

• The lighter object.

What happens to the force required if two objects have the same acceleration but different masses?

• The force required is the same for both.

• The object with less mass requires more force.

• The object with more mass requires more force.

• The object with more mass requires less force.

In the interactive game, what effect does increasing friction have on the force required to move an object?

• It has no effect on the force required.

• It increases the force required.

• It makes the object move faster.

• It decreases the force required.

What happens to acceleration if the applied force increases while mass remains constant?

• Acceleration increases.

• Acceleration becomes zero.

• Acceleration remains constant.

• Acceleration decreases.

In the game, if two objects have different masses but the same force is applied, which will have a higher acceleration?

• Both will have the same acceleration.

• The object with less mass.

• Neither will accelerate.

• The object with more mass.

What is the effect of reducing friction to 'none' in the interactive game?

• The object moves without resistance.

• The object moves slower.

• The object requires more force to move.

• The object stops moving.
