Exploring Force and Motion Concepts

What should students do if they are able to complete the lab independently?

• Watch the video for a demonstration.

• Pause the video and complete the lab on their own.

• Continue watching the video for instructions.

• Skip to the end of the video.

What is the independent variable in the experiment?

• The type of ball used

• The time it takes for the balls to travel

• The mass of the balls

• The distance the balls travel

What two types of balls are used in the experiment?

• Ping pong ball and tennis ball

• Baseball and soccer ball

• Cricket ball and basketball

• Golf ball and ping pong ball

How is the time measured for the balls to travel the distance?

• Using a ruler

• With a stopwatch

• Estimating visually

• Counting seconds aloud

What was the recorded time for the ping pong ball to travel the distance?

• 1.3 seconds

• 0.16 seconds

• 0.5 seconds

• 2 seconds

What was the recorded time for the golf ball to travel the distance?

• 2 seconds

• 1.3 seconds

• 0.5 seconds

• 0.16 seconds

Which ball traveled faster, the ping pong ball or the golf ball?

• Golf ball

• Both traveled at the same speed

• The video does not specify

• Ping pong ball

Why might the two objects be affected differently by the same strength force?

• Due to their mass

• Because of their size

• Due to their color

• Because of their shape

What is mass defined as in this experiment?

• The amount of matter an object has

• The color of an object

• The weight of an object

• The size of an object

What would likely happen if the same strength force was applied to a toy car and a full-sized car?

• The toy car would move faster

• Both would move at the same speed

• Neither would move

• The full-sized car would move faster
