Speed, velocity, acceleration

Front

What is motion?

Back

Motion is when an object changes position over time relative to a reference point.

Front

What is a reference point?

Back

A reference point is the object that appears to stay in place.

Front

What is a unit of distance?

Back

A unit of distance is a measurement used to quantify how far apart objects are, such as a kilometer.

Front

Which of the following is NOT a vector: velocity, force, speed, or 20 mph East?

Back

Speed is NOT a vector.

Front

What is speed?

Back

Speed is the distance traveled divided by the time that it takes to travel that distance.

Front

What is velocity?

Back

Velocity is speed in a given direction, making it a vector quantity.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and 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 reference point.
