True/False
Indicate whether the sentence or statement is true
or false.

|
| 1. | Adding mass to an object increases its acceleration.
|
|
| 2. | A
dual photo gate turns the timer ON when the cart flag passes the first light sensor and OFF when the
cart flag passes the second light sensor.
|
|
| 3. | This
lab illustrates Newton’s 3rd law of motion.
|
|
| 4. | The
first “run” of the low friction cart should be done with an empty cart.
|
|
| 5. | It
doesn’t matter much if rubber bands break during the use of the cart pusher.
|
|
| 6. | Using
a “cart pusher” is silly. We should just use our hands to launch the cart down the
track.
