200
What quantity is calculated by dividing distance by time?
Speed
200
An object moves 12 m east in 3 s. What is its velocity?
4 m/s east
200
What does a horizontal line on a distance‑time graph represent?
The object is stationary
200

Newton’s First Law
300
A runner travels 40 m in 10 s. What is their speed?
4 m/s
300
Why does velocity change when an object moves along a curved path, even if its speed stays constant?
Because its direction changes
300
What does the slope of a distance‑time graph represent?
Speed
300
A 2 kg object accelerates at 3 m/s². What is the net force acting on it?
6 N
300

Newton’s Third Law
400
What term describes the straight‑line change in position from start to finish?
Displacement
400
A student walks 10 m north, then 10 m south. What is their displacement?
0 m
400
What is the graph showing in terms of the objects speed?
Accelerating
400
If mass increases while force stays the same, what happens to acceleration?
It decreases
400
Which law explains why heavier objects require more force to accelerate?
Newton’s Second Law
500
If an object returns to its starting point, what quantity becomes zero even if it moved the whole time?
Displacement
500
How is the distance an object travels different from its displacement?
Distance is the total path; displacement is the straight‑line change in position.
500
On a velocity‑time graph, what does the area under the line represent?
Displacement
500
What term describes the total force acting on an object?
Net force
500
What property explains why a heavier object is harder to start moving and harder to stop once it’s moving?
Inertia
