Force Diagrams

Front

What is a force diagram?

Back

A visual representation that shows all the forces acting on an object, including their direction and magnitude.

Front

What does it mean for forces to be balanced?

Back

Forces are balanced when they are equal in size but opposite in direction, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

Forces are unbalanced when they are not equal, causing a change in motion of the object.

Front

What force opposes the motion of an object sliding on a surface?

Back

Friction.

Front

What is the normal force?

Back

The force that acts perpendicular to the surface, supporting the weight of an object resting on it.

Front

What is weight force?

Back

The force due to gravity acting on an object's mass, directed downward.

Front

What is applied force?

Back

The force that is applied to an object by a person or another object.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What happens to a hockey puck sliding on ice with no external forces?

Back

It continues to slide at a constant speed in a straight line due to inertia.

Front

What is the role of gravity in force diagrams?

Back

Gravity pulls objects downward, and its force is represented as an arrow pointing towards the center of the Earth.
