Chapter 2: Motion

Front

What does it mean to be at rest?

Back

An object is at rest when it is not moving relative to a reference point.

Front

What is the term for moving back towards the starting position?

Back

The term is 'retreating' or 'returning'.

The slant of a line on a graph is called the 'slope'.

Front

What is a projectile?

Front

What is the unit of measure for acceleration?

Back

The unit of measure for acceleration is 'meters per second squared' (m/s²).

Front

Define distance in motion.

Back

Distance is the total path length traveled by an object, regardless of direction.

Front

Define displacement in motion.

Back

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

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 is uniform motion?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.
