NET FORCE

The sum of all forces acting on an object is known as…

• Applied force

• Net force

• Normal force

• Gravitation force

Answer explanation

The overall force causes by one or many forces

An object will accelerate when there is a nonzero net force.

Which of the following is a characteristic of a balanced force?

• Equal in size, opposite in direction

• Causes a change in the direction of an object

• Causes a change in motion of an object

• Causes object to move

Answer explanation

Which of the following represents balanced forces? 

• 7N -> ->7N

• 11 N -> <- 11 N

• 8 N <- -> 4 N

• 5 -->

Which of the following represents unbalanced forces?

• 7 N -> -> 3N

• 5 N <- -> 5 N

• 2 N <- -> 2 N

• 6 <-- --> 6

Which of the following is a characteristic of an unbalanced force?

• Equal in size, opposite in direction

• Does not cause a change in motion of an object

• Causes a change in motion of an object

• No motion

Answer explanation

Calculate the Net Force:

16 N <- -> 5 N

• 12 N to the Left

• 11 N to the left

• 21 N to the left

• 9N to the right

Calculate the Net Force:

120 N --> --> 50 N

• 125 N to the left

• 12 N to the right

• 170 N to the right

• 175 to the right

Calculate the Net Force:

10 N --> <-- 4 N + <-- 7 N

• 7 N to the left

• 21 N to the right

• 1 N to the left

• 0 N

Calculate the Net Force

• 0 N

• 7 N Right

• 28 N Right

• 28 N Left

 

Calculate the Net Force

• 2 N Right

• 12 N Right

• 2 N Left

• 12 N Left
