• What time of the day are you practicing?

• How much is gravity pulling on the bat?

• How much force are you using to swing the bat?

• What type of force are you using to swing the bat?

Why are patterns so important for digital communication?

• Patterns in the code help to keep the message secret.

• Patterns help the digital device to send electrical signals.

• Patterns create a code that the sender and receiver can understand.

• People who receive the messages use the code pattern to create a new code.

All communication methods, no matter what they are, rely on what?

• patterns

• people

• pitch

• amplitude

What happens when a black marble that is moving bumps into a white marble that is at standstill on a ramp?

• The black marble stops moving and the white marble continues moving.
