Question

an example of a good conductor is _____. wood aluminum plastic to find the speed of an object, you need to know ___ and time. motion distance volume if the result of calculating acceleration is a negative number, an object is ________. accelerating decelerating moving uphill the formula for calculating force is _____. mass x acc

Explanation:

1. Good conductors allow easy flow of electricity; metals like aluminum are good conductors, while wood and plastic are insulators.
2. The speed formula is $speed = \frac{distance}{time}$, so distance and time are required.
3. Negative acceleration means the object's velocity is decreasing, which is deceleration.
4. Newton's second law states force equals mass multiplied by acceleration.

Answer:

1. B. aluminum
2. B. distance
3. B. decelerating
4. mass × acceleration (mass X acc)
