Types of Forces (Contact)

Front

What is the force acting in the ropes of the swing?

Back

Tension is the force that is transmitted through the rope when it is pulled tight by forces acting from opposite ends.

Front

What is a force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, causing a change in motion of an object.

Front

What are contact forces?

Back

Contact forces are forces that occur when two objects are in direct contact with each other.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between surfaces.

Front

How can you reduce friction?

Back

Friction can be reduced by using a smooth surface, lubrication, or by reducing the force pressing the surfaces together.

Front

What is normal force?

Back

Normal force is the support force exerted upon an object that is in contact with another stable object, acting perpendicular to the surface.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses, such as the Earth and an object.

Front

What is tension in a rope?

Back

Tension is the pulling force transmitted along the length of a rope or string when it is pulled tight.
