A student records the time and distance for a moving object and plots the data on a graph. How can the student determine the average speed from the graph?
By finding the area under the graph
By dividing the total distance by the total time
By counting the number of points
By measuring the highest point
A distance-time graph shows a curved line. What does this indicate about the object’s motion?
The object is moving at a constant speed

Compare the physical properties of comets and asteroids.
Both are made mostly of ice
Comets are icy and have tails; asteroids are rocky and do not have tails
Both orbit the Sun in the Kuiper Belt
Asteroids are icy and comets are rocky
Explain how gravity affects the motion of meteors as they enter Earth’s atmosphere.
Gravity slows down meteors
Gravity pulls meteors toward Earth, increasing their speed
Gravity pushes meteors away from Earth
Gravity has no effect on meteors

Why do moons orbit planets instead of the Sun directly?
The Sun’s gravity is weaker than the planet’s gravity
The planet’s gravity is stronger for objects close to it
Moons are repelled by the Sun
Moons do not experience gravity
On a distance-time graph, the line becomes steeper as time increases. What does this indicate?
