# PS.10 b - Newton's Laws

The student will investigate and understand the scientific principles of work, force, and motion. Key concepts include
b) Newton’s laws of motion.

Bloom's Levels:  Analyze; Understand

### BIG IDEAS

• Motion is a key characteristic of all matter that can be observed, described, and measured.
• Energy change can be understood in terms of forces- pushes or pulls.

• I can explain why, when two objects collide, they often bounce backwards.
• I can design a roller coaster

### UNDERSTANDING THE STANDARD

• Newton’s three laws of motion describe the motion of all common objects.
• Mass and weight are not equivalent. Mass is the amount of matter in a given substance. Weight is a measure of the force due to gravity acting on a mass. Weight is measured in newtons.

### ESSENTIALS

In order to meet this standard, it is expected that students will

b) identify situations that illustrate each Law of Motion.

a-d) differentiate between mass and weight.

### KEY VOCABULARY

speed, velocity, acceleration, Newton's Laws of Motion, work, force, mechanical advantage, efficiency, power, mass, weight, simple machines, compound machine
