Force and Motion Flashcard

Front

What is force?

Back

A push or pull on an object that can cause it to change its motion.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is speed?

Back

The distance traveled by an object in a given amount of time, usually expressed in meters per second (m/s).

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is inertia?

Back

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

Front

What is acceleration?

Back

The rate at which an object changes its velocity.

Front

What is the relationship between force and acceleration?

Back

According to Newton's second law, Force = Mass x Acceleration (F = ma).

Front

What is a balanced force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Forces that are not equal, causing a change in motion.
