1. FORCE & MOTION

2. Topic 7: Forces and Changes in Motion Benchmarks
SC.5.P.13.1 Identify familiar forces that cause objects to move, such as pushes or pulls, including gravity acting on falling objects.
SC.5.P.13.2 Investigate and describe that the greater the force applied to it, the greater the change in motion of a given object.
SC.5.P.13.3 Investigate and describe that the more mass an object has, the less effect a given force will have on the object's motion.
SC.5.P.13.4 Investigate and explain that when a force is applied to an object but it does not move, it is because another opposing force is being applied by something in the environment so that the forces are balanced.
SC.5.N.2.1 Recognize and explain that science is grounded in empirical observations that are testable; explanation must always be linked with evidence.
LACC.5.SL.1.1 Engage effectively in a range of collaborative discussions (one-on-one, in groups, and teacher-led) with diverse partners on grade 5 topics and texts, building on others’ ideas and expressing their own clearly.

3. What is MOTION? A change in the position of an object.
Sometimes it may involve a change in direction, too.
Engage: Demonstrate with the hyperlink video: change in direction,. Discuss the motion in the clip art. Demo motion with objects and students.

4. What changes motion?
Motion of an object changes when a force acts upon the object.
An object remains in motion, or at rest, unless a force acts on it.

5. Pushing and Pulling A force is a push or pull.
Unit 7 Lesson 1 What Are Forces?
Pushing and Pulling
A force is a push or pull.
Forces can change the movement of an object.
Forces can change the shape of an object.

Pushing and Pulling
Weight is a measure of the force gravity exerts on an object.
Spring scales are used to measure force in units called newtons (N).

7. What conditions can affect force and motion?
Amount of mass
Type of force applied
Type of surface texture
Surface area
Moon
Earth

If the same force is applied, objects with greater mass accelerate slower than objects with less mass.

9. Unit 7 Lesson 1 What Are Forces?
I’m Not Moving!
The larger the force applied to an object, the greater the acceleration is.
The less an object’s mass is, the less force is needed to change its motion.
