Sec 4: Understanding Gravity and Its Effects

Front

What is the value of the acceleration due to gravity on Earth?

Back

10 m/s²

Front

What is the primary reason objects fall to the ground on Earth?

Back

Gravitational force

Front

What happens to the gravitational force if the distance between two objects is doubled?

Back

It becomes one-fourth

Front

Which of the following best defines gravity?

Back

A force that attracts objects towards each other

Front

A penny is dropped from your class. It is falling...

Back

Vertically towards the center of our earth

Front

What is the formula for calculating gravitational force between two objects?

Back

F = G * (m1 * m2) / r²

Front

What does 'G' represent in the gravitational force formula?

Back

The universal gravitational constant, approximately 6.674 × 10⁻¹¹ N(m/kg)²

Front

How does mass affect gravitational force?

Back

Gravitational force increases with the mass of the objects.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between objects increases.

Front

What is weight?

Back

The force exerted by gravity on an object, calculated as weight = mass × gravity.
