Question

directions: read the words on the left. then, read the definitions on the right. match the correct vocabulary word to the correct definition by drawing a line.

1. speed ___
2. motion ___
3. velocity ___
4. force ___
5. kinetic energy ___
6. inertia ___
7. balanced force ___
8. potential energy ___
9. friction ___
10. unbalanced force ___
11. gravity ___
12. acceleration ___

a. how fast an objects position changes over time at any given moment.
b. the speed and direction of an object.
c. a change in velocity over time.
d. change in an objects position.
e. a push or pull
f. the tendency of an object in motion to stay in motion or of an object at rest to stay at rest.
g. a force between two surfaces that slows objects or stops them from moving.
h. object at rest
i. object in motion
j. energy in motion.
k. a type of energy that is stored in an object due to its position relative to other objects.
l. a noncontact force

Explanation:

To solve this vocabulary - matching problem related to force and motion, we analyze each term and its corresponding definition:

1. Motion

The definition of motion is a change in an object's position. Among the given options, option d says "change in an object's position". So, Motion should be matched with d.

2. Velocity

Velocity is defined as the speed and direction of an object. Option b states "the speed and direction of an object", so Velocity is matched with b.

3. Kinetic Energy

Kinetic energy is the energy that an object possesses due to its motion, that is, energy in motion. Option j says "energy in motion", so Kinetic Energy is matched with j.

4. Inertia

Inertia is the tendency of an object in motion to stay in motion or of an object at rest to stay at rest. Option f has this description, so Inertia is matched with f.

5. Friction

Friction is a force between two surfaces that slows objects or stops them from moving. Option g gives this definition, so Friction is matched with g.

6. Unbalanced Force

An unbalanced force causes an object to be in motion. Option i says "Object in motion", so Unbalanced Force is matched with i.

7. Gravity

Gravity is a non - contact force (it acts at a distance without direct contact between objects). Option l says "A noncontact force", so Gravity is matched with l.

8. Acceleration

Acceleration is a change in velocity over time. Option c has this definition, so Acceleration is matched with c.

Final Matches:

1. Motion - d
2. Velocity - b
3. Kinetic Energy - j
4. Inertia - f
5. Friction - g
6. Unbalanced Force - i
7. Gravity - l
8. Acceleration - c

3. Kinetic Energy

Kinetic energy is the energy that an object possesses due to its motion, that is, energy in motion. Option j says "energy in motion", so Kinetic Energy is matched with j.

4. Inertia

Inertia is the tendency of an object in motion to stay in motion or of an object at rest to stay at rest. Option f has this description, so Inertia is matched with f.

5. Friction

Friction is a force between two surfaces that slows objects or stops them from moving. Option g gives this definition, so Friction is matched with g.

6. Unbalanced Force

An unbalanced force causes an object to be in motion. Option i says "Object in motion", so Unbalanced Force is matched with i.

7. Gravity

Gravity is a non - contact force (it acts at a distance without direct contact between objects). Option l says "A noncontact force", so Gravity is matched with l.
