RDG PASSAGE SPEED

What is the difference between distance and displacement?

• Distance is the total path length, while displacement is the straight line between two points.

• Distance is always shorter than displacement.

• Displacement includes direction, but distance does not.

• Distance is measured in time, while displacement is measured in speed.

Understanding

Explain how speed and velocity are different from each other.

• Velocity measures distance traveled over time, while speed measures direction.
• Speed and velocity are the same and can be used interchangeably.
• Speed is a quantity; velocity is a quantity without direction.

• Speed is a ratio of distance to time; velocity is speed in a specific direction

Speed is the ratio of distance traveled to the amount of time taken. It can be measured in ___ per hour.

• miles or kilometers
• liters per hour
• seconds per hour
• grams per hour

What is the formula for speed?

• Speed = Distance - Time
• Speed = Time / Distance
• Speed = Distance / Time
• Speed = Distance x Time

Which of the following best describes velocity?

• Speed in a specific direction.

• The total distance traveled over time.

• The average speed of an object.

• The change in speed over time.

Understanding

Evaluate the statement: 'Two objects with the same speed but opposite directions have the same velocity.'

• True
• They have different speeds
• They have the same acceleration
• False

Velocity is speed in a specific ___.

• direction
• distance

• time

• velocity

What does a zero displacement indicate about an object's motion?

• The object has stopped moving completely.
• The object is accelerating in a straight line.
• The object is moving at a constant speed.
• The object has returned to its starting point.

How is speed defined in physics?

• Speed is the distance traveled per unit of time.
• Speed is the force applied to an object.
• Speed is the total energy of an object.
• Speed is the rate of acceleration.

In a velocity diagram, what does a steeper slope typically represent?

• Higher acceleration
• Constant speed
• Lower velocity
• NO acceleration
