Dynamics of Forces

Front

What is the definition of mass?

Back

The amount of matter in an object.

Front

What happens to an object's velocity when it is in circular motion?

Back

It is constantly changing.

Front

What is the term for the force that one object exerts on another by touching it?

Back

Applied force.

Front

What is the state of an object in free fall?

Back

It is said to be weightless.

Front

What does gravitational attraction depend on?

Back

Mass and distance between objects.

Front

What is inertia?

Back

The resistance of an object to change its state of motion.

Front

What is the difference between mass and weight?

Back

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

Front

What is terminal velocity?

Back

The constant speed an object reaches when the force of gravity is balanced by the drag force.

Front

What is microgravity?

Back

A condition in which objects appear to be weightless and experience very little gravitational force.

Front

What is the formula for calculating weight?

Back

Weight = mass × gravitational acceleration (W = mg).
