,Studied planetary motion Johannes Keller
Studied uniform and accelerated motions Galileo Galilei
When two chunks of matter interact, they influence Force
each other. These influences are commonly called
pushes or pulls. What is the formal name of these
influences?
After carefully reading Newton's third law of motion, The two forces are always equal in magnitude under all conditions.
what conditions does it place on the equality of the two
forces resulting from an interaction?

force on the table and the table applies an upward
force on the block. How do these two forces compare
in magnitude?
A large truck moving at 30 m/s (67 mph) collides into a The two forces are in opposite directions with the two forces having equal

and the truck continues at a slightly slower speed and
merges back into the driving lane. The interaction
between the truck and sign results in the truck applying
a force on the sign and the sign applying a force on the
truck. Which of the following properly relates these two
forces?
Mass is a measure of inertia. Inertia is a property of all of the above.
