Flashcard: Newton's Laws & Gravity 2024

Front

What does the strength of gravity between two objects depend upon?

Back

The strength of gravity depends on the mass of the objects and the distance between them.

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

How does gravity affect objects of different masses?

Back

Gravity pulls on all objects equally, regardless of their mass, but heavier objects experience a greater force.

Front

What happens to an object's weight on the Moon compared to Earth?

Back

An object's weight is less on the Moon due to the Moon's weaker gravitational pull.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is gravitational attraction?

Back

Gravitational attraction is the force that pulls two objects toward each other due to their masses.

Front

What is inertia?

Back

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

Front

What is the effect of air resistance on falling objects?

Back

Air resistance opposes the motion of falling objects, affecting their acceleration and speed.
