6.7A Identifying Forces

Front

What are the two forces acting on a man sitting on a chair?

Back

The force of the chair acting upwards and the force of gravity acting downwards.

Front

What type of force is applied force?

Back

Applied force is an example of a contact force.

Front

Define a NON-CONTACT force.

Back

A NON-CONTACT force is a push or pull force where the objects are not touching.

Front

What affects the rate of acceleration of a feather and a marble when dropped from the same height?

Back

Air resistance (friction) affects the feather more than the marble.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

Give an example of a contact force.

Back

An example of a contact force is friction, which occurs when two surfaces rub against each other.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What happens when two equal forces act in opposite directions?

Back

They create a balanced force, resulting in no change in motion.
