Speed, Velocity, Acceleration

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be classified as speeding up, slowing down, or changing directions.

Front

What is speed?

Back

Speed is how much distance is covered over a period of time.

Front

What is velocity?

Back

Velocity is speed in a given direction; it includes both magnitude and direction.

Front

What is a vector?

Back

A vector is a quantity that has both magnitude (a number) and direction.

Front

What is a scalar?

Back

A scalar is a quantity that has only magnitude and no direction.

Front

What is motion?

Back

Motion is a change in position with respect to a reference point.

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 (only magnitude), while velocity is a vector quantity (magnitude and direction).

Front

What does it mean to accelerate?

Back

To accelerate means to change the velocity of an object, which can involve speeding up, slowing down, or changing direction.

Front

What is uniform motion?

Back

Uniform motion is when an object moves at a constant speed in a straight line.
