S8P3.a Explain Recap

Front

What is the definition of an object in motion?

Back

An object is considered in motion if it changes its position relative to a reference point.

Front

What is velocity?

Back

Velocity is the speed of an object in a given direction.

Front

What does it mean when an object is at a steady speed?

Back

An object is at a steady speed when it covers equal distances in equal intervals of time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity, which can involve increasing speed, decreasing speed, or changing direction.

Front

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

Back

An object is at constant speed when it travels the same distance in the same amount of time.

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 happens to an object that is accelerating?

Back

An object that is accelerating is either increasing its speed, decreasing its speed, or changing its direction.

Front

What is a frame of reference?

Back

A frame of reference is a system for specifying the precise location of objects in space and time.

Front

What does it mean for an object to be stationary?

Back

An object is stationary if it is not changing its position relative to a reference point.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.
