Representing Motion

Front

What is velocity?

Back

Velocity is a vector quantity that refers to the rate at which an object changes its position. It has both magnitude and direction.

Front

How do you calculate velocity?

Back

Velocity (v) is calculated using the formula: v = displacement / time.

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the 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 includes both speed and direction.

Front

What does a particle model motion diagram represent?

Back

A particle model motion diagram uses dots to represent the position of an object at equal time intervals, showing its motion.

Front

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

Back

An object moving at a constant speed covers equal distances in equal intervals of time, regardless of the direction.

Front

What is a vector?

Back

A vector is a quantity that has both magnitude and direction, such as velocity or force.

Front

What is a scalar?

Back

A scalar is a quantity that has only magnitude and no direction, such as speed or mass.

Front

How do you represent vectors graphically?

Back

Vectors are represented graphically by arrows, where the length of the arrow indicates the magnitude and the direction of the arrow indicates the direction.

Front

What is the significance of the length of a vector?

Back

The length of a vector should be proportional to its magnitude, allowing for visual comparison of different vectors.
