Free Body Diagrams & Net Forces practice

What is a Free Body Diagram (FBD)?

Back

A Free Body Diagram is a graphical representation used to visualize the forces acting on an object. It shows all the external forces acting on the body, including their direction and magnitude.

What does the force of gravity depend on?

Back

Front

What is the net force?

Back

Front

What is equilibrium in terms of forces?

Back

Equilibrium occurs when the net force acting on an object is zero, meaning all forces are balanced, and the object remains at rest or moves at a constant velocity.

How do you calculate the normal force?

Back

Front

What is the direction of the force of gravity?

Back

The force of gravity always acts downward towards the center of the Earth.

Front

What happens to an object when the net force is not zero?

Back

When the net force is not zero, the object will accelerate in the direction of the net force, resulting in a change in its motion.

What is the formula for calculating weight?

Front

What is the significance of the negative sign in the force of gravity?

Back

The negative sign indicates that the force of gravity acts in the downward direction, opposite to the positive direction defined in the coordinate system.

Front

What is the difference between mass and weight?

Back

Mass is a measure of the amount of matter in an object and is constant regardless of location, while weight is the force exerted by gravity on that mass and can change depending on the gravitational field strength.
