6.1.2 Gravity & Inertia

Front

What is weight?

Back

Weight is how strongly your body is being pulled down by gravity.

Front

What does inertia tell us about a resting object?

Back

Because of inertia, a resting object will remain at rest.

Front

What is gravity?

Back

Gravity is the attraction of one particle or body to another.

Front

What is required to get an object moving or to make it stop?

Back

A force is required to get an object moving or to make it stop.

Front

What happens to the pull of gravity as the distance between objects increases?

Back

The pull of gravity decreases as the distance between objects increases.

Front

Define inertia in your own words.

Back

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

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object's mass.

Front

How does gravity affect objects in free fall?

Back

In free fall, all objects accelerate towards the Earth at the same rate due to gravity, regardless of their mass.

Front

What is the formula for calculating weight?

Back

Weight can be calculated using the formula: Weight = mass × gravitational acceleration (W = mg).

Front

Explain how gravity varies with distance.

Back

Gravity decreases with the square of the distance between two objects; as distance increases, gravitational force decreases.
