Explain the difference between positive and negative acceleration.
Positive acceleration means the object is at rest, while negative acceleration means the object is moving at a constant speed.
Positive acceleration means the object is slowing down, while negative acceleration means the object is speeding up.
Positive acceleration means the object is moving in a straight line, while negative acceleration means the object is moving in a curved path.
Positive acceleration means the object is speeding up, while negative acceleration means the object is slowing down.
How can you calculate acceleration if you know the initial velocity, final velocity, and time?
acceleration = (final velocity - initial velocity) * time
acceleration = (final velocity * initial velocity) / time
acceleration = (final velocity - initial velocity) / time
acceleration = (final velocity + initial velocity) / time

A bowling ball and a bag of potato chips are dropped at the same time from a tall tower on Earth. What happens?
Both speed up but the bag of chips is affected by the air resistance more so the bowling ball hits the ground first.
Both speed up but the bowling ball is affected by the air resistance more so the bag of chips hits the ground first.

A bowling ball and a bag of potato chips are dropped at the same time from a tall tower on the Moon. There is no air on the Moon. What happens?
Both speed up but the bag of chips is not as heavy so the bowling ball hits the ground first.
Both speed up but the bowling ball has more inertia (resistance to the pull of gravity) so the bag of chips hits the ground first.
Both hit the surface at the same time because light and heavy objects fall at the same speed when there is no air resistance.
