Forces and free body diagrams

Front

What is the net force?

Back

The net force is the sum of all forces acting on an object, determining its motion. It can be balanced (zero) or unbalanced (causing acceleration).

Front

What type of force is used to push an object?

Back

Applied Force is the force exerted by a person or another object to move something.

Front

What is a balanced force?

Back

Balanced forces occur when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Unbalanced forces occur when the forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

What is the difference between contact force and non-contact force?

Back

Contact forces require physical contact between objects (e.g., friction), while non-contact forces act at a distance (e.g., gravity).

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

What is air resistance?

Back

Air resistance is a type of frictional force that opposes the motion of an object through the air.

Front

What is a free body diagram?

Back

A free body diagram is a visual representation showing all the forces acting on an object, helping to analyze the net force.

Front

How do you calculate net force?

Back

To calculate net force, add all the forces acting in one direction and subtract the forces acting in the opposite direction.

Front

What happens when the net force is zero?

Back

When the net force is zero, the object remains at rest or continues to move at a constant velocity.
