The direction could be described as being north, south, east, west or left, right, up, down. Which of these statements represent a vector description? Include all that apply.Įxpressions of vector quantities would include a magnitude (number, value, etc.) and a direction. Numerical values and directions are stated for a variety of quantities. Displacement, velocity (both average and instantaneous), and acceleration all require the mention of a direction in order to fully describe the quantity. Of the five kinematic quantities listed here (distance, displacement, speed, velocity and acceleration), three of them are vectors.

Which of the following quantities are vectors? Include all that apply. Scalars and Vectors || Vectors and DirectionĢ. TRUE - This is exactly the case and exactly what is done throughout the unit. Direction is of no importance when adding scalars.ĭ. The direction of a vector must be considered when adding two vectors together. The rules for adding vectors together are unique to vectors and cannot be used when adding scalars together. FALSE - Both vectors and scalars can be added together. If a quantity did have a direction associated with it, then that quantity would not be a vector.Ĭ. Scalars have no regard for direction and it is meaningless to associate a direction with such a quantity. FALSE - Scalars are defined as quantities which are fully described by their magnitude alone. If it didn't, then it would NOT be a vector.ī. By definition, a vector has a direction associated with it. TRUE - Vectors are defined as quantities which are fully described by both their magnitude and direction.

Vectors can be represented by an arrow on a scaled diagram the length of the arrow represents the vector's magnitude and the direction it points represents the vector's direction.Ī.

Vectors can be added together scalar quantities cannot.

A scalar quantity can have a direction associated with it.

A vector quantity always has a direction associated with it.

Which of the following statements are true of scalars and vectors? List all that are TRUE.

To do this, we separate projectile motion into the two components of its motion, one along the horizontal axis and the other along the vertical. Since vertical and horizontal motions are independent, we can analyze them separately, along perpendicular axes. Keep in mind that if the cannon launched the ball with any vertical component to the velocity, the vertical displacements would not line up perfectly.

You can see that the cannonball in free fall falls at the same rate as the cannonball in projectile motion. Figure 5.27 compares a cannonball in free fall (in blue) to a cannonball launched horizontally in projectile motion (in red). The most important concept in projectile motion is that when air resistance is ignored, horizontal and vertical motions are independent, meaning that they don’t influence one another. Ask students to guess what the motion of a projectile might depend on? Is the initial velocity important? Is the angle important? How will these things affect its height and the distance it covers? Introduce the concept of air resistance. Review addition of vectors graphically and analytically.
