Front

What is a Vector?

Back

A quantity that has both a number and direction, such as velocity. Represented by a line with an arrow; the longer the line, the larger the vector force (magnitude).

Front

What is Speed?

Back

The rate of change of an object's position, measured as distance traveled over time.

Front

What are Unbalanced Forces?

Back

Forces that are not balanced, causing an object to move or change its motion.

Front

What is Velocity?

Back

The rate of change of displacement, which includes both speed and direction.

Front

What is the Point of Origin?

Back

The starting location from which an object begins its motion.

Front

What is Friction?

Back

A force that opposes the motion of an object, acting parallel to the surfaces in contact.

Front

What is Force?

Back

A push or pull acting on an object, measured in Newtons (N). It can cause an object to accelerate.

Front

What is Motion?

Back

The change in position of an object over time.

Front

What is Inertia?

Back

The tendency of an object to resist changes in its state of motion; an object at rest stays at rest, and an object in motion stays in motion.

Front

What is Acceleration?

Back

The rate of change of velocity of an object, which can be caused by a change in speed or direction.
