Unit 4: Speed, velocity and Acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time, without considering the direction.

Front

What is velocity?

Back

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

Front

How does acceleration occur?

Back

Acceleration occurs when an object speeds up, slows down, or changes direction.

Front

What is the difference between speed and velocity?

Back

The main difference is that velocity includes direction, while speed does not.

Front

If a car is moving at 60 mph, what is this an example of?

Back

This is an example of speed.

Front

If a car is moving 60 mph to the north, what is this an example of?

Back

This is an example of velocity.

Front

What happens to the velocity of an object when it changes direction?

Back

The velocity changes because velocity includes direction.

Front

What is constant speed?

Back

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

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.
