Unit 3 - TEKS 7.7A-D

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What happens to an object in motion when balanced forces act on it?

Back

The object will continue moving at a constant speed.

Front

What happens to an object at rest when no unbalanced force acts on it?

Back

It will remain at rest.

Front

What does a steep slope on a distance-time graph indicate?

Back

Fast speed.

Front

What is the definition of velocity?

Back

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

Front

Which is an example of velocity?

Back

30 m/s east.

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

Calculate the average speed of a car that travels 150 kilometers in 3 hours.

Back

50 km/h.

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 is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate, change direction, or change its state of motion.
