Final Review - Forces

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

How does distance affect gravitational force between two objects?

Back

The gravitational force decreases with the square of the distance between the objects.

Front

What does the weight of an object represent?

Back

The force of gravity acting on the object.

Front

What is an example of Newton's First Law of Motion?

Back

An object in motion stays in motion unless acted upon by an external force.

Front

How do you calculate net force?

Back

Net force is the sum of all forces acting on an object.

Front

What is the formula for gravitational force?

Back

F = G * (m1 * m2) / r^2, where G is the gravitational constant.

Front

What is lift force?

Back

The upward force that opposes the weight of an object in a fluid.

Front

What happens to an object's motion when a net force is applied?

Back

The object will accelerate in the direction of the net force.

Front

What is inertia?

Back

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 of gravity on an object, calculated as weight = mass * gravity.
