Practice: Newton's Laws & Gravity 2024

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

What is Newton's First Law of Motion?

Back

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

Front

What is inertia?

Back

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

Front

What does Newton's Second Law of Motion state?

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 the formula for calculating gravitational force?

Back

The gravitational force (F) between two objects is calculated using the formula F = G * (m1 * m2) / r^2, where G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers.

Front

What is the role of mass in gravitational attraction?

Back

The greater the mass of an object, the stronger its gravitational pull.

Front

What is the role of distance in gravitational attraction?

Back

The greater the distance between two objects, the weaker the gravitational force between them.

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is a planet's orbit?

Back

A planet's orbit is the path it takes around a star, such as the Earth orbiting the Sun, which is maintained by the balance of gravitational force and inertia.

Front

What is a push force?

Back

A push force is a force that moves an object away from the source of the force.
