A bowling ball leaves a bowler's hand. An accelerometer inside the ball reads zero. Which of the following best describes what happens to the ball?

A. The ball speeds up.

B. The ball moves at a constant speed.

C. The ball curves toward the gutter.

D. The ball slows down.

Not quite sure what this means :( Thanks!! @perl :)

Answer 1

if acceleration is zero, then velocity is constant (or speed is constant)

Answer 2

ohh okay, so B?

Answer 3

think of physics. remember if there is no net force on an object, then it will either continue traveling in a line (constant speed), or it will remain at rest if it was at rest originally

Answer 4

yes B

Answer 5

awesome! thanks @perl :)

Answer 6

i think thats called the law of inertia?

Answer 7

or newtons first law

Answer 8

ohh okie :)
