Understanding Kinematics in Motion

What is the difference between distance and displacement?

• Distance is the total path length; displacement is the shortest straight-line distance with direction.

• Distance includes direction while displacement does not.

• Displacement measures the total distance traveled.

• Distance is always greater than displacement.

Define speed and how it differs from velocity.

• Speed and velocity are the same and can be used interchangeably in all contexts.

• Speed is a vector quantity that includes direction; velocity is a scalar quantity measuring distance over time.

• Speed is the rate of change of position; velocity is the total distance traveled.

• Speed is a scalar quantity measuring distance over time; velocity is a vector quantity that includes direction.

What is acceleration? Give an example.

• An example of acceleration is a car increasing its speed from 20 m/s to 60 m/s in 5 seconds.

• A car moving at a constant speed of 50 m/s.

• A train traveling in a straight line without changing speed.

• A bicycle coming to a complete stop.

What do we call a decrease in speed?

• speeding up

• acceleration

• velocity increase

• deceleration

How can we represent motion graphically?

• Motion can be represented using position-time, velocity-time, and acceleration-time graphs.

• Motion cannot be represented graphically.

• Motion can only be represented using bar charts.

• Motion is best represented with pie charts.

What is uniform motion? Provide an example.

• A bicycle accelerating down a hill.

• An example of uniform motion is a car traveling at a constant speed of 60 km/h on a straight highway.

• A train coming to a complete stop at a station.

• A person walking in a zigzag pattern.

Explain non-uniform motion with an example.

• A bicycle moving in a straight line without changing speed.

• An example of non-uniform motion is a car accelerating from rest to a higher speed.

• A train moving at a constant speed of 60 km/h.

• A ball rolling down a smooth, flat surface at a steady pace.

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 does the slope of a distance-time graph represent speed?

• The slope of a distance-time graph represents speed.

• The slope of a distance-time graph represents time.

• The slope of a distance-time graph shows acceleration.

• The slope of a distance-time graph indicates direction.

What is the formula for calculating average speed?

• Average Speed = Total Distance + Total Time

• Average Speed = Distance x Time

• Average Speed = Total Time / Total Distance

• Average Speed = Total Distance / Total Time
