![]() ![]() |Įngineers apply basic physics concepts of inertia and force in a variety of situations, such as in designing structures and vehicles of all shapes and sizes.

In order to share information with other people, these choices must also be shared.Įxplanations of stability and change in natural or designed systems can be constructed by examining the changes over time and forces at different scales. ![]() For any given object, a larger force causes a larger change in motion.Īlignment agreement: Thanks for your feedback! All positions of objects and the directions of forces and motions must be described in an arbitrarily chosen reference frame and arbitrarily chosen units of size. The greater the mass of the object, the greater the force needed to achieve the same change in motion. The motion of an object is determined by the sum of the forces acting on it if the total force on the object is not zero, its motion will change. Plan an investigation individually and collaboratively, and in the design: identify independent and dependent variables and controls, what tools are needed to do the gathering, how measurements will be recorded, and how many data are needed to support a claim.Īlignment agreement: Thanks for your feedback! Science knowledge is based upon logical and conceptual connections between evidence and explanations.Īlignment agreement: Thanks for your feedback! This lesson focuses on the following Three Dimensional Learning aspects of NGSS: Plan an investigation to provide evidence that the change in an object's motion depends on the sum of the forces on the object and the mass of the object.Ĭlick to view other curriculum aligned to this Performance Expectation Apply Newton's first law to explain the effect of applying a force on an object.Compare and contrast speed, velocity and acceleration.Identify and give examples of (types of) forces. ![]() State and explain Newton's first law of motion. ![]() Learning how Newton's laws apply in everyday situations enables students to describe how objects move and helps prepare them for the study of more complex physics concepts.Īfter this lesson, students should be able to: For example, engineers design the seat belts in cars to keep passengers from being thrown from vehicles in the event of a crash, which occurs as a consequence of Newton's first law. This engineering curriculum aligns to Next Generation Science Standards ( NGSS).Įngineers apply basic physics concepts such as Newton's laws of motion to a wide range of problem-solving situations, including the design of structures and vehicles. This lesson is the first in a series of three lessons that are intended to be taught as a unit. Through a PowerPoint® presentation and some simple teacher demonstrations these fundamental science concepts are explained and illustrated. They also learn that engineers consider and take advantage of these forces and laws of motion in their designs. Students learn the difference between speed, velocity and acceleration, and come to see that the change in motion (or acceleration) of an object is caused by unbalanced forces. Examples of contact and non-contact types of forces are provided, specifically applied, spring, drag, frictional forces, and magnetic, electric, gravitational forces. Students are introduced to the concepts of force, inertia and Newton's first law of motion: objects at rest stay at rest and objects in motion stay in motion unless acted upon by an unbalanced force. ![]()
