S8P3.a Explain Recap

Front

What is the definition of velocity?

Back

Velocity is speed in a given direction.

Front

What does it mean for an object to be moving at a constant speed?

Back

An object is moving at a constant speed if it covers equal distances in equal intervals of time.

Front

What does a position vs. time graph indicate about an object's motion?

Back

A position vs. time graph shows how the position of an object changes over time, indicating whether it is accelerating, moving at a constant speed, or not moving.

Front

What is acceleration?

Back

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

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What does it mean for an object to be stationary?

Back

An object is stationary if it is not moving and its position does not change over time.

Front

How can you determine if an object is speeding up?

Back

An object is speeding up if its velocity is increasing over time.

Front

What does it mean for an object to be slowing down?

Back

An object is slowing down if its velocity is decreasing over time.

Front

What is a frame of reference?

Back

A frame of reference is a set of coordinates or a background against which motion is measured.
