Physics Chapter 5

What are the 2 major components?

-horizontal -vertical

The equation for speed

5t^2

What two things are required of a vector quantity?

Direction and Magnitude

Can a scalar quantity be made into a vector quantity by adding a direction to its magnitude?

NO. Because if you add direction to something like time, volume or temperature (etc) it wont make sense.

Velocity is a what quantity?

Vector

Acceleration

Vector Quantity

Momentum

Vector Quantity

An airplane flies in the same direction as the wind. The velocity of the airplane is the sum of the

airplane's velocity relative to he air and the winds velocity relative to the ground.

Any vector can be resolved, or broken, into an equivalent set of two ________ vectors at right angle to each other.

component

Ignoring air resistance,the horizontal component of velocity of a horizontally launched projectile remains

constant.

Equation for the distance a projectile falls below its imaginary straight line path is

d=1/2gt^2

At the beginning of the projectile's trajectory, the magnitude of the vertical component of the velocity is

greater than the magnitude of the horizontal component of the velocity.

Sketches in physics often include arrows, in which each arrow represents the _____ and the ____ of a quantity.

magnitude direction

When friction is negligible, a rolling all

moves at a constant velocity

A projectile

moves through air or space

The path of a projectile with constant horizontal motion and downward acceleration due to gravity is a

parabola

Component vectors are always at..

right angles to each other.

For a projectile, the horizontal component of its motion is like

the horizontal motion of a ball freely rolling on a level surface without friction.

The path of a projectile is also called its

trajectory

The vertical component of velocity for the projectile at the peak of its trajectory is

zero
