Chapter 2 Study Guide

Front 1

1.Definition of Balanced Force?

Back 1

When the net force on an object is zero

Front 2

2.What is the definition of Contact Force?

Back 2

A force that is exerted only when two objects are touching.

Front 3

3. What is the definition of Force?

Back 3

A push or pull

Front 4

4.What is the definition of Net Force?

Back 4

The combination of all the forces acting on an object

Front 5

5.What is the definition of Newton’s first law of motion?

Back 5

If the net force on an object is zero, an object at rest remains at rest, or, if the object is moving ,it continues to move in a straight line with constant speed

Front 6

6.What is the definition of non contact force?

Back 6

A force that one object exerts on another when they are not touching

Front 7

7.What is the definition of unbalanced force?

Back 7

When the net force on an object is not zero

Front 8

8.What is the definition of Compression Force?

Back 8

Is a squeezing force applied to an object that can make an object shrink

Front 9

9.What is the definition of elastic force?

Back 9

Is the force exerted by a material when it is stretched or compressed

Front 10

10.What is the definition of Friction?

Back 10

Is a force that opposes the movement between two surfaces in contact

Front 11

11.What is the definition of gravity?

Back 11

Is an attractive force that exists between all objects that have mass

Front 12

12.What is the definition of law of universal gravitation?

Back 12

All objects are attracted to each other with a force that depends on the masses of the objects and the distance between them

Front 13

13.What is the definition of normal force?

Back 13

Is a force exerted by an object that is perpendicular to the surface of the object

Front 14

14. What is the definition of tension force?

Back 14

Is a pulling force applied to an object that can make the object stretch

Front 15

15.What is the definition of weight?

Back 15

Is the gravitational force exerted on an object

Front 16

16. What is the definition of centripetal force?

Back 16

Is the force that is perpendicular to the velocity and toward the center of the circle

Front 17

17.What is the definition of Newton’s second law of motion?

Back 17

The acceleration of an object equals the net force divided by the object’s mass

Front 18

18. What is the definition of Newton’s third law of motion?

Back 18

When one object exerts a force on a second object, the second object exerts an equal force in the opposite direction on the first object
