Practice Flashcard: Displacement/Velocity/Acceleration

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction.

Front

Define velocity.

Back

Velocity is the rate at which an object changes its position, including both speed and direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object over time.

Front

What is a frame of reference?

Back

A frame of reference is a point or object used to determine if another object is in motion.

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance/Time).

Front

What does a horizontal line on a distance-time graph represent?

Back

A horizontal line indicates that the object is at rest and not changing its position.

Front

What does a steep slope on a distance-time graph indicate?

Back

A steep slope indicates a high speed, meaning the object is covering a large distance in a short amount of time.

Front

What happens to an object's velocity when it accelerates?

Back

When an object accelerates, its velocity changes, which can mean an increase or decrease in speed or a change in direction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that only considers how fast an object is moving, while velocity is a vector quantity that includes direction.

Front

What does it mean for an object to be in motion?

Back

An object is in motion if its position changes relative to a frame of reference over time.
