Sec 4: Understanding Gravity and Its Effects

Front

What is gravity?

Back

A force that attracts objects towards each other.

Front

What effect does air resistance have on a falling object?

Back

It decreases the speed of the object.

Front

How is gravitational force related to mass?

Back

Gravitational force is directly proportional to the mass of the objects.

Front

Which factor does NOT affect gravitational force?

Back

The shape of the objects.

Front

What is the formula for gravitational force between two masses?

Back

Front

What is the gravitational constant (G)?

Back

A constant used in the calculation of gravitational force, approximately equal to 6.674 × 10^-11 N(m/kg)^2.

Front

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

Back

The gravitational force decreases.

Front

What is the relationship between distance and gravitational force?

Back

Gravitational force is inversely proportional to the square of the distance between the objects.

Front

What is weight?

Back

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

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s².
