Unit #2 Motion, Displacement, Vectors

Front

What has both size and direction?

Back

Vector

Front

What is the net force when 100 N is applied to the left and 230 N to the right?

Back

130 N to the right

Front

What is relative motion?

Back

The motion of an object in comparison to other objects in a specific frame of reference.

Front

What does a vector provide?

Back

Both direction and distance.

Front

What do we call the sum of 2 or more vectors?

Back

Resultant vector.

Front

What is a scalar quantity?

Back

A quantity that has only magnitude and no direction.

Front

What is displacement?

Back

The shortest distance from the initial to the final position of an object, including direction.

Front

What is the difference between distance and displacement?

Back

Distance is a scalar quantity representing the total path length, while displacement is a vector quantity that considers direction.

Front

What is the formula for calculating the resultant vector?

Back

R = √(A² + B² + 2AB cos θ), where A and B are the magnitudes of the vectors and θ is the angle between them.

Front

What is the significance of the origin in motion?

Back

The origin is the reference point from which the position of an object is measured.
