Physics Flashcard

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What changes as a ball accelerates?

Back

The velocity of the ball changes.

Front

What does gravitational force depend on?

Back

Gravitational force depends primarily on the mass of the object.

Front

What is Newton’s 2nd law of motion?

Back

Newton’s 2nd law of motion states that Force equals Mass times Acceleration (F=MA).

Front

What pulls falling objects toward Earth?

Back

Gravity pulls falling objects toward Earth.

Front

What is speed?

Back

Speed is how fast an object is moving, regardless of direction.

Front

What is acceleration?

Back

Acceleration is the rate at which an object's velocity changes.

Front

What is inertia?

Back

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

Front

What is mass?

Back

Mass is the amount of matter in an object.

Front

What is free fall?

Back

Free fall is when an object is falling under the influence of gravity only.
