Distance, Speed, Acceleration Test Review

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

Define acceleration.

Back

Acceleration is the rate of change of velocity 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 does it mean for an object to be in motion?

Back

An object is in motion if its position changes relative to another object.

Front

What is the unit of acceleration in the SI system?

Back

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

Front

If a car travels 300 m in 15 seconds, what is its speed?

Back

Speed = 300 m / 15 s = 20 m/s.

Front

What is constant speed?

Back

Constant speed means an object covers equal distances in equal intervals of time.

Front

What is the effect of gravity on falling objects?

Back

Gravity causes objects to accelerate downwards at approximately 9.81 m/s².

Front

What is the term for the change in velocity over time?

Back

Acceleration.

Front

How can you determine if an object is accelerating?

Back

If the object's speed or direction changes, it is accelerating.
