Speed, Velocity, Acceleration

Front

What is speed?

Back

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

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

What is velocity?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

If an object is moving at a constant speed, is it accelerating?

Back

No, an object moving at a constant speed is not accelerating unless it changes direction.

Front

What happens to acceleration when an object slows down?

Back

When an object slows down, it is still accelerating, but the acceleration is negative (deceleration).

Front

Is changing direction considered acceleration?

Back

Yes, changing direction is considered a form of acceleration.

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

If a cyclist travels 22 km in 2 hours, what is their speed?

Back

Speed = Distance / Time = 22 km / 2 h = 11 km/h.

Front

True or False: Acceleration can occur even if the speed of an object remains constant.

Back

True, if the direction changes.
