Unit 1 Test Study Guide
Forces and Motion
Use the quizlet to review key terms for the unit: https://quizlet.com/ aae19c?x=1jqt&i=15xisq
3 Laws of Motion Flipbook
Answer the questions below. Refer to your notes (1-3 in notebook and 4 on GC), the slideshow, and the Quizlet
to help.
Section 1: Position and Motion
1. What information do you need to describe your position?
Your location and speed
2. How can you determine motion?
You can see where something is going
3. What is speed and how do you determine speed?
Speed is how fast something is going. It can be found by seeing how many units in a certain time an object
can go.
4. What is the difference between velocity and speed?
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an
object's movement.
Section 2: Acceleration and Force
1. What is contact force?
The force from contact between two objects
2. What is friction?
The force stopping things while the roll along something.

4. What is a free body diagram? Draw an example. How do you find net force?
It is a diagram showing all of the different forces acting upon an object.
3. What is the difference between balanced and unbalanced forces?
Balanced forces have a net force equal to zero while unbalanced forces are not zero, resulting in a change in
motion.
Section 3: Force Pairs
1. What are two types of collision forces? How are they different?
11
Elastic collisions and inelastic collisions. An elastic collision is when objects bounce off of eachother due to
the collision. An inelastc collision is when the colliding objects become distorted and might stick to eachother. 2. What is the difference between Action - Reaction forces and balanced forces?
Balanced forces, which are also equal and opposite, cancel out because they act on the same object.
Action andreaction forces, in contrast, act on different objects, so they don't cancel out.
3. What is a normal force?
The proce acting perpendicular to a surface.
Section 4: Gravitational Forces
1. What is a noncontact force?
A force that doesnt involce contact between two objects such as gravity.
2. What is gravity?
The force from the earth pulling things back down to its core.
3. What are two things that affect gravitational forces?
Friction and air resistance.
4. What tool can be used to measure force?
A scale
5. What is the difference between weight and mass?
Weight is the amount of gravitation force while mass is an objects density.
6. What is gravitational acceleration?
The acceleration gravity puts on an object.
