Question 1

Which of the following best describes displacement in the context of motion?

Accepted Answer

Displacement is the change in position seen as direction.

Question 2

A car moves along a straight road from point A to point B, then returns to point A. If the total distance traveled is 100 km, what is the car's displacement?

Accepted Answer

$$0\ \mathrm{km}$$

Question 3

Which graph type is best used to visualize how an object's speed changes over time?

Accepted Answer

Velocity vs. time graph

Question 4

If the slope of a position vs. time graph increases, what does this indicate about the object's motion?

Accepted Answer

The object is speeding up.

Question 5

Which of the following equations correctly defines velocity?

Accepted Answer

$$v = \frac{\Delta x}{\Delta t}$$

Question 6

A runner moves rightward with a positive velocity. What does a negative velocity indicate?

Accepted Answer

The runner is moving leftward.

Question 7

Acceleration is best defined as:

Accepted Answer

The rate of change of velocity.

Question 8

Which equation represents acceleration?

Accepted Answer

$$a = \frac{\Delta v}{\Delta t}$$

Question 9

Question 11

A ball is thrown upward and returns to its starting point. Which statement about its displacement is true?

Accepted Answer

Displacement is zero.

Question 12

If an object’s velocity changes from $$5\ \mathrm{m/s} to$$ $$15\ \mathrm{m/s} in$$ $$2\ \mathrm{s}$$, what is its acceleration?

Accepted Answer

$$5\ \mathrm{m/s^2$}$$

Question 13

Which of the following best describes trajectory?

Accepted Answer

Trajectory is the path an object takes as it moves.

Question 14

A position vs. time graph for a moving car shows a straight line with a constant positive slope. What does this indicate about the car’s motion?

Accepted Answer

The car is moving at a constant velocity.

Question 15

Which of the following is NOT one of the four basic types of motion?

Accepted Answer

Oscillatory

Question 16

A student walks 3 meters east, then 4 meters west. What is the student’s displacement?

Accepted Answer

$$-1\ \mathrm{m}$$

Question 17

If the velocity of an object is constant, what is its acceleration?

Accepted Answer

$$a = 0$$

Question 18

A car accelerates from rest at $$2\ \mathrm{m/s^2$}$$ for $$5\ \mathrm{s}. $$What is its final velocity?

Accepted Answer

$$10\ \mathrm{m/s}$$

Question 19

Which of the following best describes speed?

Accepted Answer

Speed is the distance traveled per unit time.

Question 20

A train moves leftward with a velocity of $$-20\ \mathrm{m/s}. $$What does the negative sign indicate?

Accepted Answer

The train is moving in the opposite direction to the positive axis.
