Lesson #11
E.Q:How do Free Body Diagrams help us analyze forces and predict an object's motion in real-world scenarios?

Lesson Objectives:
- Students will understand what a Free Body Diagram (FBD) is.
- Students will be able to draw FBDs for different physical situations.
- Students will be able to apply the concept of FBDs to solve force and motion problems.

Multiple Choice

What do the arrows or vectors represent?

forces acting on the object

all the acceleration acting on the object

all the ways an object can move

Multiple Choice

Is force a vector?

yes

Board demonstration

Multiple Choice

A skier has reached the bottom of a hill and is coasting to the right while slowing down along the loosely-packed snow. Ignore air resistance.

What is the direction of the FRICTION force?

There's no friction force

Multiple Choice

A skier has reached the bottom of a hill and is coasting to the right while slowing down along the loosely-packed snow. Ignore air resistance.

What is the direction of the NORMAL force?

There's no normal force

Multiple Choice

A downward-moving skydiver who has just opened the parachute is slowing down.

Ignore air resistance.

What is the direction of the TENSION force?

There's no tension force

Multiple Choice

A rightward force is applied to a dresser to accelerate it to the right across the bedroom floor. Ignore air resistance.

What is the direction of the APPLIED force?

There's no applied force

Multiple Select

A hockey puck glides to the right across the ice at a constant speed. Ignore air resistance.

Which forces are the same?

Normal force

Friction force

Gravity force

Applied force

Multiple Choice

Multiple Choice

What is the NET FORCE of this diagram?

17 N, right

17 N, leftvvv

23 N, right

12 N, up

Multiple Choice

F_g & F_app

F_b & F_g

F_g & F_N

F_f & F_N

HOMEWORK

Problem 1: A 5 kg object is at rest on a table. Draw the FBD.
Problem 2: A 3 kg object is being pushed to the right with a force of 10 N on a frictionless horizontal surface. Draw the FBD and find the acceleration of the object.
Problem 3: A 2 kg object slides down an inclined ramp 30° with the horizontal, with friction being 10% of the normal force. Draw the FBD, find the friction force and the acceleration of the object.
