Speed, Velocity, and Acceleration Review

Front

What is constant speed?

Back

Constant speed refers to the speed of an object that does not change over time.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can be positive (speeding up) or negative (slowing down).

Front

What does it mean when an object is in motion?

Back

An object is in motion when it changes its position relative to a reference point.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is deceleration?

Back

Deceleration is a type of acceleration that occurs when an object slows down, resulting in a negative acceleration.

Front

How do you calculate acceleration?

Back

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

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

What is the unit of speed in the metric system?

Back

The unit of speed in the metric system is meters per second (m/s).

Front

What happens to the velocity of an object when it turns a corner at constant speed?

Back

The velocity changes because velocity includes direction, and turning changes the direction of the object.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.
