Gravity and Motion

Front

What occurs when only gravity is acting on an object?

Back

Free fall is the motion of an object when it is falling solely under the influence of gravity.

Front

What is mass?

Back

Mass is the amount of matter in an object.

Front

What does the strength of the force of gravity depend on?

Back

The strength of the force of gravity depends on the mass of the objects and the distance between them.

Front

What is orbital motion a combination of?

Back

Orbital motion is a combination of free fall and forward motion.

Front

What does gravity do?

Back

Gravity attracts all objects towards each other.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed an object reaches when the force of gravity is balanced by air resistance.

Front

What is projectile motion?

Back

Projectile motion is the motion of an object that is thrown into the air and is influenced by gravity.

Front

How does distance affect gravitational force?

Back

As the distance between two objects increases, the gravitational force between them decreases.

Front

What is the formula for calculating weight?

Back

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