Question

types of forces practice problems
objectives:
a. students know the definition of different types of forces.
b. students will find the net force and describe the magnitude and direction of the net force.
c. students will describe the different types of forces and how it affects the object’s motion.
directions: write the type of force that matches with each description below.
air resistance friction normal force applied force
gravity tension spring force

1. ______________________ is a type of force that a person or machine exerts (pushes or pulls) on an object that may cause a change in the velocity of an object.
2. _________________ or weight is defined as the force of attraction between the earth and all objects that are on earth due to their masses. the two factors that affect this force are mass and the distance.
3. ______________________ is a type of force exerted on an object that is in contact with another object, such as a table, shelf, cabinet or the ground. this force acts in the opposite direction of gravity.
4. ______________________ is a force that acts in the opposite direction of a nonmoving (static) or moving (kinetic) object. this force can cause an object to slow down and stop.
5. ______________________ is a type of friction force that acts on objects as they travel through the air. this force often acts in the opposite direction of gravity.
6. ______________________ results when an object is pulled or stretched by a string, rope, cable, or wires.
7. ______________________ is exerted when a spring scale stretches or compresses once an object is attached to it.

Explanation:

Question 1

The description is about a force exerted by a person or machine (push/pull) to change an object's velocity. Applied force is defined as such a force.

The force of attraction between Earth and objects due to mass (and distance) is gravity (weight is related to gravity).

A force on an object in contact with another (like table/ground) acting opposite to gravity is the normal force.

Answer:

applied force
