Speed, Velocity, Momentum Definitions ONLY 2024

Front

What is speed?

Back

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

Front

What is the formula to calculate velocity?

Back

Velocity is calculated using the formula: displacement/time.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity.

Front

What is the unit of momentum?

Back

The unit of momentum is kg·m/s or km/hr x Kg.

Front

What does the term 'displacement' mean?

Back

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

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 is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

What is the formula to calculate acceleration?

Back

Acceleration is calculated using the formula: Change in velocity / Change in time.

Front

What is the principle of Conservation of Momentum?

Back

The principle states that in a closed system, the total momentum before an event is equal to the total momentum after the event.

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has only magnitude, such as speed.
