Understanding Kinematics in Motion

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?

• -1

• 0

• 1

• 9.8
