What is speed?

How does speed relate to motion?
Motion- Speed, Direction, & Velocity
Position, direction, and speed are some of the important factors that describe an object's motion. What is position?
● Position is the direction and distance the object is from a point of reference.
What is direction?
● Direction is the straight-line path from a reference point to the object's position. Direction
is very closely related to position. What is motion?
Motion is the change in an object's position over time relative to a reference point. An object in motion always changes its position and may change its direction.
SPEED
An object's speed is the distance it travels divided by the time it takes to travel
that distance
Objects can move at different speeds. Faster objects move farther than slower
objects if both objects move for the same amount of time.
Calculating Speed
If a car traveled 150 miles at a constant speed in 5 hours,
at what speed was it traveling?
DIRECTION
Direction is the path along which something is moving. Direction can be
described using words, such as
●
up or down
●
left or right
Velocity
Velocity describes both the speed of an object and the direction in which it is
traveling
When an object is traveling at constant velocity, this means it is traveling
with a constant speed and direction. A change in object's velocity can be

Answer the following questions in google classroom.
1.
What is the formula for calculating speed?
Position & Reference Points
❏
An object's position must be given relative to something else. The
place from which its position is measured is called a reference point
❏
The position of an object can be described in relationship to a reference
point, such as a certain location or another object.
❏
Distance is the length between two positions or locations.
❏
Speed is how the position of an object changes over time.
Force & Motion
The motion of an object can be changed by an unbalanced force. The way that the movement changes depends on the strength of the force pushing or pulling and the mass of the object. Forces have both a direction and a magnitude (size).
Force and Mass
A force is a push or a pull that acts on an object and may change its motion. Forces are needed to start, stop, or change the direction of an object's motion. The more force that is applied to an object, the greater the change in the object's motion. In other words, the harder an object is pushed, the faster it will move.
if the same amount of force is used to move two objects with different masses, the object with less mass will move faster.
Friction & Gravity
❏
Friction is a force that opposes motion. If an object is already moving, friction
can slow it down or make it stop
❏
Gravity is the force of attraction that exists between any two objects that have
mass. Gravity keeps the planets orbiting around the Sun, and it pulls objects
on Earth toward the Earth's center.
❏
Gravity depends on the mass of the objects and the distance between them.
The gravity we feel from Earth is very strong because we are close to the
Earth and the mass of the Earth is very large.

Answer the following questions in google classroom.
1. What is distance?
2. Describe the difference between a balanced force and unbalanced force
NET FORCE
❏ A net force is the total unbalanced force acting on an object. A net force has a certain
strength, or magnitude, and a direction. If the net force is not zero, then it will cause the object to speed up, slow down or change direction.
❏ Balanced forces have equal magnitudes (sizes) but opposite directions.
❏ When the forces on an object are balanced, the object does not accelerate because the
net force is zero/ When this happens, the object can either be moving at a constant velocity or at rest.
❏ Unbalanced forces have unequal magnitudes and/or directions. Unbalanced forces
result in net forces that are not zero. An unbalanced force will change an object's speed and/or direction.

SCIENCE DISCUSSION
QUESTION
Distance
❏
Distance is the length between two positions or locations.
❏
Distance can be measured in meters, yard, inches, or
centimeters with rulers, measuring tapes, or meter sticks.
Position vs. Time Graphs
❏
Motion is a key characteristic of all matter that can be observed, described,
measured, and graphed.
❏
An object's position is the object's displacement from a certain reference point.
If the object is at the reference point, its position is 0. If an object has a position
of 5 meters, that means it is 5 meters away from the reference point.
❏
As an object moves, its position changes through time. The relationship between
position and time can be shown on a graph. A straight line on a position vs. time
graph represents on object moving at a constant speed.
