Newtons 1st law
A book is lying on a table. What will happen to the book if no external force is applied?
The book will remain at rest.
What is the formula for Newton's second law?
F=ma
A block of weight is placed on a table. The table surface exerts an upward force on the block.
The block exerts a force of on the table.
What is Newton's first law of motion also known as?
Law of Inertia
A ball develops a certain amount of acceleration after being hit.
Horizontal Acceleration
when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air. What force is that?
Normal Force
Describe newtons first law of motion.
Newton's first law, also called the law of inertia, states that an object at rest will remain at rest, and an object in motion will continue moving in a straight line at a constant speed unless acted upon by an external force; essentially, an object will resist changes in its state of motion unless a force compels it to change.
When a truck is moving backwards.
Negative Acceleration
Describe friction
Friction, force that resists the sliding or rolling of one solid object over another.
Other name for Newton's second law Is
Law of Force and Acceleration
