Intro to Forces

Front

What is an Applied Force?

Back

A force applied to an object by another object.

Front

What is Gravitational Force?

Back

The force of the Earth (or any massively large object) attracting another object to itself.

Front

What does Newton's Second Law state?

Back

F = ma (Force equals mass times acceleration).

Front

What happens to acceleration as mass increases, assuming force is constant?

Back

Acceleration decreases.

Front

Calculate the acceleration of a box with a net force of 200 N and mass of 40 kg.

Back

5 m/s².

Front

What is Friction Force?

Back

The force that opposes the motion of an object.

Front

What is Tension Force?

Back

The force transmitted through a string, rope, or wire when it is pulled tight.

Front

What is Drag Force?

Back

The resistance force experienced by an object moving through a fluid.

Front

Define Net Force.

Back

The overall force acting on an object when all individual forces are combined.

Front

What is Inertia?

Back

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