Two students walk the same distance, but one takes more time. Who has a greater speed?
The student who takes less time
On a velocity-time graph, what does a line sloping downward mean?
The object is slowing down
If two objects have the same force applied, but one has more mass, which accelerates more?
The object with less mass
What happens to gravitational potential energy as an object falls?
It decreases
A science table has a mass of 12 kg. A chair has a mass of 4,000 g. Which object has more mass?
The table; 12 kg = 12,000 g
Can an object have a displacement of zero but still travel a distance? How?
Yes; if it returns to its starting point
Two objects are shown on a velocity-time graph. One has a larger area under the graph. Which object traveled farther and why?
The object with the larger area; area represents distance
A book pushes down on a table. According to Newton’s Third Law, what force pair is acting?
The book pushes on the table, and the table pushes up on the book with equal force
Explain how energy changes when a ball is thrown straight up and comes back down.
KE → PE on the way up; PE → KE on the way down
