Amplify Force and Motion End of Unit Flashcard

Front

What is force?

Back

Force is a push or pull on an object that can cause it to change its velocity (speed or direction).

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in kilograms or grams.

Front

How does mass affect force?

Back

The greater the mass of an object, the more force is required to change its motion.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can be an increase or decrease in speed.

Front

What is the relationship between force and acceleration?

Back

According to Newton's second law, force equals mass times acceleration (F = ma).

Front

What is inertia?

Back

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

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the principle of conservation of momentum?

Back

The principle states that the total momentum of a closed system remains constant if no external forces act on it.

Front

What is a net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined.
