Speed, Velocity, Distance, Displacement

Front

What is the definition of distance in physics?

Back

Distance is a scalar quantity that represents the total length of the path traveled by an object, regardless of direction.

Front

What is the definition of displacement?

Back

Displacement is a vector quantity that represents the shortest distance from the initial to the final position of an object, along with the direction.

Front

How do speed and velocity differ?

Back

Speed is a scalar quantity that measures how fast an object is moving, while velocity is a vector quantity that measures the rate of change of an object's position in a specific direction.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the formula for calculating distance?

Back

Distance = Speed x Time.

Front

What is the formula for calculating displacement?

Back

Displacement = Final Position - Initial Position.

Front

If a car travels 100 km north in 2 hours, what is its speed?

Back

Speed = 100 km / 2 hours = 50 km/h.

Front

If a person walks 3 km east and then 4 km west, what is their displacement?

Back

Displacement = 3 km east - 4 km west = -1 km (1 km west).

Front

What is the speed of an object that travels 150 meters in 30 seconds?

Back

Speed = 150 m / 30 s = 5 m/s.

Front

What is the velocity of an object that moves 20 meters to the south in 4 seconds?

Back

Velocity = 20 m / 4 s = 5 m/s south.
