FLASHCARD QUESTION

Front

What is a force diagram?

Back

A force diagram, also known as a free-body diagram, is a graphical representation that shows all the forces acting on an object. It helps visualize the interactions between the object and its environment.

FLASHCARD QUESTION

Front

What forces act on a dropped object near Earth's surface?

Back

The primary force acting on a dropped object near Earth's surface is gravity, which pulls the object downward. Air resistance is negligible in this scenario.

3.

FLASHCARD QUESTION

Front

What is the effect of air resistance on falling objects?

Back

Air resistance opposes the motion of falling objects, reducing their acceleration. However, if it is negligible, the object accelerates downward at 9.81 m/s² due to gravity.

FLASHCARD QUESTION

Front

What does it mean for an object to be in motion?

Back

An object is in motion when its position changes relative to a reference point over time.

5.

FLASHCARD QUESTION

Front

What is the relationship between force and motion?

Back

Force is a push or pull that can cause an object to accelerate, change direction, or change shape. According to Newton's second law, force equals mass times acceleration (F=ma).

FLASHCARD QUESTION

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

FLASHCARD QUESTION

Front

What is the significance of a net force in a force diagram?

Back

The net force is the vector sum of all forces acting on an object. It determines the object's acceleration and direction of motion.
