What is the difference between distance and displacement?
Distance is always greater than displacement.
Distance and displacement are the same concept.
Distance is the total path length traveled; displacement is the shortest straight-line distance with direction.
Displacement measures the total distance traveled regardless of direction.
Define speed and provide its formula.
Speed = Distance / Time
Speed = Time / Distance
Speed = Distance x Time
Speed = Distance + Time
What is the difference between speed and velocity?
Speed can be negative, while velocity cannot.
Speed is scalar; velocity is vector (includes direction).
Speed is always greater than velocity.
Velocity measures distance only, not direction.
How do you calculate acceleration?
a = v_i / t
a = (v_f + v_i) * t
a = (v_f - v_i) / t
a = v_f + v_i
What does a negative acceleration indicate?
Negative acceleration signifies a constant speed without any change.
Negative acceleration means the object is moving faster in the same direction.
Negative acceleration indicates an increase in speed.
Negative acceleration indicates deceleration or a decrease in speed.
If a car travels 100 meters in 5 seconds, what is its speed?
20 meters per second
30 meters per second
25 meters per second
15 meters per second
What is the formula for calculating average velocity?
Average Velocity = Total Time / Total Displacement
Average Velocity = Total Distance / Total Time
Average Velocity = Total Displacement / Total Time
Average Velocity = Initial Velocity + Final Velocity
Explain what a velocity-time graph represents.
A velocity-time graph represents the force acting on an object.
A velocity-time graph indicates the temperature changes of an object.
A velocity-time graph shows the position of an object over time.
A velocity-time graph shows how velocity changes over time, indicating acceleration and displacement.
What does the slope of a distance-time graph indicate?
The slope represents the time taken.
The slope shows the direction of the object.
The slope indicates the speed of the object.
The slope indicates the distance traveled.
If an object is at rest, what is its acceleration?

What are the three equations of motion?
1. v = u + at; 2. s = ut + 0.5at²; 3. v² = u² + 2as
v = u - at
s = ut - 0.5at²
s = vt + 0.5at²
How can you determine the distance traveled from a velocity-time graph?
Count the number of grid squares on the graph.
Add the velocity values at each time interval.
Measure the slope of the graph.
Calculate the area under the velocity-time graph.
What is uniform motion?
Motion that varies in speed and direction.
Motion in a circular path at varying speeds.
Motion that involves acceleration and deceleration.
Uniform motion is motion at a constant speed in a straight line.
Describe the motion of an object with constant acceleration.
The object moves at a constant speed in a straight line.
The object experiences no change in velocity over time.
The object moves with a continuously changing velocity, following a parabolic path in position vs. time graphs.
The object's motion is described by a circular path in position vs. time graphs.
How does deceleration differ from acceleration?
Deceleration is the same as acceleration.
Acceleration can only be positive and never negative.
Deceleration always occurs in a downward direction.
Deceleration is negative acceleration, indicating a decrease in speed, whereas acceleration indicates an increase in speed.
