Newton's third law states that
An object at rest tends to stay at rest, and an object in motion tends to stay in motion, with the same direction and speed.
For every action, there is an equal and opposite reaction.
Force equals mass times acceleration
Newton's second law states that
An object at rest tends to stay at rest, and an object in motion tends to stay in motion, with the same direction and speed.
For every action, there is an equal and opposite reaction.
Force equals mass times acceleration

The image below shows two opposite forces acting during Tug-a-war, what can we say is true about the effect of the forces on the cart?
It cannot be determined without knowing which team is stronger.
The forces are unbalanced, and net force on the rope moves it to the left.
It cannot be determined because one team looks stronger than the other.
The forces are unbalanced, and net force on the rope moves it to the right.

a change in velocity
how fast or slow something is moving
What is speed?
how hot or cold something is
how fast or slow something is moving
a force that acts to pull an object down to earth
how short or tall something is
What is acceleration?
a change in velocity
putting the pedal to the metal
a change in speed
a change in position
What is motion?
emotion-e

Match the description to the graph:
"The car is stopped."
Match the description to the graph:
"The car is traveling at a constant speed."
Segment A-B The bus is _________________.
at rest
returning (to original position)
moving forward
What is the equation to calculate speed?
Speed = distance/time
Distance = time/speed
Speed = distance x velocity
Speed = distance x time
