Front

What is the formula for gravitational force between two masses?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

Front

What is Newton's Third Law of Motion?

Back

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

Front

How does distance affect the gravitational force between two objects?

Back

The gravitational force decreases with the square of the distance between the two objects.

Front

What is the definition of acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's Second Law, F = m * a, where F is force, m is mass, and a is acceleration.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What does a velocity-time graph represent?

Back

A velocity-time graph shows how the velocity of an object changes over time.

Front

How do you calculate the distance traveled from a velocity-time graph?

Back

The distance traveled is equal to the area under the velocity-time graph.

Front

What is the concept of action and reaction forces?

Back

Action and reaction forces are pairs of forces that are equal in magnitude and opposite in direction.

Front

What is the definition of mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg).
