speed, velocity and acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s) or kilometers per hour (km/h).

Front

What is the formula to calculate speed?

Back

Speed = distance/time

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

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 per unit of time, measured in meters per second squared (m/s²).

Front

What is the formula for acceleration?

Back

Acceleration = (final velocity - initial velocity) / time

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.

Front

If a car's speed changes from 20 m/s to 10 m/s in 5 seconds, what is its acceleration?

Back

Acceleration = (10 m/s - 20 m/s) / 5 s = -2 m/s².

Front

How do you calculate the distance traveled if you know speed and time?

Back

Distance = speed x time.

Front

If a person jogs at a speed of 6 km/h for 1 hour, how far do they travel?

Back

Distance = 6 km/h x 1 h = 6 km.
