How are distance,time, and speed related ?

• Speed, distance and time are proportional

• the process of changing position

• the rate at which someone or something is able to move or operate

• Speed, being a scalar quantity, is the rate at which an object covers distance

define position reference point and motion

• Movement

• motion: the process of changing position

• Levi running

• Speed

speed

• True

• If an object moves along a straight line, the distance travelled can be represented by a distance-time graph

• A car going slow

• we turned onto the runway and began to gather speed

How are speed and average speed different

• Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio.

• the physical quantity that has both directions as well as magnitude

• Volume

• Vector

Can you read a distance time graph?

• Climbing

• If an object moves along a straight line, the distance travelled can be represented by a distance-time graph

• Running

• if the total force on the object is not zero, its motion will change

What is a vector quantity?

• any quantity that has magnitude and direction, such as displacement or velocity

• What is a vector quantity?

What is velocity?

• quantity that designates how fast and in what direction a point is moving.

• Lake Maracaibo in Venezuela

• Power drains rob the car battery of its total

• Leatherback sea turtle

How does motion change?

• Motion changes when there is a change in speed, direction, or both.
• Motion changes when there is a change in speed only.
• Motion changes when there is a change in direction only.
• Motion changes when there is no change in speed or direction.

• What is acceleration?

• The rate of change of velocity of an object with respect to time.
• The force exerted on an object
• The distance traveled by an object in a given time
• The amount of matter in an object
