Newtons laws
Newtons first law is also known as the law of____.
What is Inertia?
True or false: A force is defined as a push or pull on an object?
What is true?
A 10 kg book is resting on a table. What is the force of static friction acting on the book if someone tries to push it with a force of 5 N, but the book doesn't move? Why?
The book doesn't move because the force applied is not strong enough to move the book.
