CBA #2: Motion TEKS 7.7 ABCD

Front

What is the definition of balanced forces?

Back

Balanced forces are two or more forces acting on an object that cancel each other out, resulting in no change in motion.

Front

What happens to an object at rest when balanced forces act on it?

Back

An object at rest will remain at rest when balanced forces act on it.

Front

What is the formula to calculate distance in a straight line?

Back

Distance = Speed x Time.

Front

If David walks 3 km north and then 4 km east, what is the total distance traveled?

Back

The total distance traveled is 7 km.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight-line distance from the starting point to the endpoint.

Front

How does friction affect the motion of an object?

Back

Friction opposes the motion of an object, and more friction decreases speed.

Front

What is the significance of a displacement graph?

Back

A displacement graph shows how the position of an object changes over time.

Front

What does it mean if the displacement of an object is 0 m?

Back

It means that the object has returned to its starting position.

Front

What is the role of gravity in motion?

Back

Gravity is a force that pulls objects toward the center of the Earth, affecting their motion.

Front

How can you determine the speed of an object?

Back

Speed can be determined by dividing the distance traveled by the time taken.
