31 lessons teach this standard. Every lesson is interactive, and every one prints as a worksheet with a separate answer key.
Physical Science · Chapter 5 · Lesson 1
Distance, Displacement, Speed, Velocity
Run a lap and your displacement is zero.
Physical Science · Chapter 5 · Lesson 2
Acceleration and Motion Graphs
Slowing down is acceleration too.
Physical Science · Chapter 5 · Lesson 3
Force causes acceleration, not motion.
Physical Science · Chapter 5 · Lesson 4
A falling object stops accelerating long before it lands.
Physics · Chapter 1 · Lesson 1
Some quantities need a direction to mean anything.
Physics · Chapter 1 · Lesson 2
Average and instantaneous are different numbers.
Physics · Chapter 1 · Lesson 3
A change in velocity, in any respect.
Physics · Chapter 1 · Lesson 4
Not a picture of the journey.
Physics · Chapter 1 · Lesson 5
Mass does not appear in the answer.
Physics · Chapter 2 · Lesson 1
Components can be handled one at a time.
Physics · Chapter 2 · Lesson 2
Two motions happening at once and ignoring each other.
Physics · Chapter 2 · Lesson 3
Velocity is always relative to something.
Physics · Chapter 2 · Lesson 4
Accelerating without changing speed.
Physics · Chapter 3 · Lesson 1
Motion needs no cause. Changing it does.
Physics · Chapter 3 · Lesson 2
Acceleration follows the net force, divided by mass.
Physics · Chapter 3 · Lesson 3
The pair acts on two different objects.
Physics · Chapter 3 · Lesson 4
The force that made the first law hard to see.
Physics · Chapter 3 · Lesson 5
One object, and only what touches it.
Honors Physics · Chapter 1 · Lesson 1
Split a quantity into two that do not interfere.
Honors Physics · Chapter 1 · Lesson 2
Four equations, one assumption, and where it comes from.
Honors Physics · Chapter 1 · Lesson 3
Gradients and areas say everything the equations do.
Honors Physics · Chapter 1 · Lesson 4
Two independent motions sharing one clock.
Honors Physics · Chapter 1 · Lesson 5
Every velocity is measured with respect to something.
Honors Physics · Chapter 2 · Lesson 1
Free-Body Diagrams for Systems
One diagram per object, and every force needs an owner.
Honors Physics · Chapter 2 · Lesson 2
Tilt the axes, not your head.
Honors Physics · Chapter 2 · Lesson 3
One rope, one tension, two objects.
Honors Physics · Chapter 2 · Lesson 4
A force that is whatever it needs to be, up to a limit.
Honors Physics · Chapter 2 · Lesson 5
A force that grows until it stops the acceleration.
Honors Physics · Chapter 5 · Lesson 1
The same four equations, with new letters.
Honors Physics · Chapter 5 · Lesson 2
Where you push matters as much as how hard.
Honors Physics · Chapter 5 · Lesson 3
Mass matters, and where it sits matters more.
