Newton's  Laws

Learning Targets

3.01B - I can apply Newton's first law (law of inertia) to make predictions in physical situations.
3.02A - I understand the relationship between net force, mass, and acceleration.
3.03B - I can describe how Newton’s 3rd Law applies to physical situations and identify 3rd law pairs.

Can You...

  • (3.01B) Newton’s First Law, the law of inertia. An object will continue to move at a constant velocity unless it feels an unbalanced push or pull.
    • Therefore, objects acted upon by balanced forces will not accelerate -- they instead remain at constant velocity.
    • “Inertia” refers to an object’s “resistance” to change in its constant velocity motion. Inertia is not an interaction between objects, and therefore inertia is not a force.
  • (3.02A) Newton's 2nd Law: The net force on an object divided by its mass equals its acceleration, or
  • Fnet = m·a
    • When the forces acting on an object are unbalanced, the object will accelerate. Because acceleration is a change in velocity, and velocity includes both speed and direction, a net force will change the speed and/or the direction of an object's motion.
  • (3.03B) Newton’s Third Law: Forces are interactions that can be described in pairs of equal magnitude acting in opposite directions on the two objects. Fby A on B = -Fby B on A

"There is no science in this world like physics. Nothing comes close to the precision with which physics enables you to understand the world around you. It's the laws of physics that allow us to say exactly what time the sun is going to rise. What time the eclipse is going to begin. What time the eclipse is going to end."
