What is the difference between distance and displacement?
Distance is the force exerted on an object, while displacement is the momentum of the object.
Distance is the rate of change of velocity, while displacement is the resistance to a change in motion.
Distance is the speed of an object, while displacement is the direction of its motion.
Distance is how far an object has moved, while displacement is the difference in starting and ending point.
What is the formula for calculating average speed?
Total time traveled divided by total distance traveled
Total time traveled multiplied by total distance traveled
Total distance traveled multiplied by total time traveled
Total distance traveled divided by total time traveled
What does the slope on a distance vs. time graph represent?
Acceleration of the object

What is the Law of Conservation of Momentum?
Momentum is not affected by collisions

What is the difference between balanced and unbalanced forces?
Balanced forces have a net force of 0 N, while unbalanced forces have a net force of 1 N

Melanie is accelerating as she skates on the ice. However, the speed at which she is skating has not changed. A possible explanation for this is that Melanie
is changing directions as she skates in a circle
is skating in a straight line
has reached the top speed at which she can skate
has stopped skating and is now standing still

going down the hill
coasting on the straight track
slowing down at the end of the ride
