Speed, Velocity, Acceleration

Front

What is the definition of speed?

Back

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

Front

How is velocity different from speed?

Back

Velocity is a vector quantity that includes both the speed of an object and its direction of motion.

Front

What does it mean to accelerate?

Back

To accelerate means to change the velocity of an object, which can occur by speeding up, slowing down, or changing direction.

Front

What is the formula for calculating acceleration?

Back

Acceleration can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is constant speed?

Back

Constant speed means that an object travels the same distance in equal intervals of time.

Front

What happens to an object's velocity when it accelerates?

Back

When an object accelerates, its velocity changes; it can increase, decrease, or change direction.

Front

What is the relationship between speed and time in a distance-time graph?

Back

In a distance-time graph, the slope represents speed; a steeper slope indicates a higher speed.

Front

What is the unit of measurement for acceleration?

Back

The unit of measurement for acceleration is meters per second squared (m/s²).

Front

What does a negative acceleration indicate?

Back

Negative acceleration, also known as deceleration, indicates that an object is slowing down.

Front

How can you determine if an object is in motion?

Back

An object is in motion if its position changes relative to a reference point over time.
