Newton's Laws Test Review

Front

What is Newton's second law of motion?

Back

Newton's second law states that acceleration is produced when a force acts on a mass. The formula is F = ma, where F is force, m is mass, and a is acceleration.

Front

What happens to the pull of gravity as the product of two objects' masses increases?

Back

The pull of gravity increases.

Front

What will an object at rest do if no outside forces are applied?

Back

An object at rest will stay at rest.

Front

What is an example of Newton's third law of motion?

Back

When a soccer player kicks a ball, the ball exerts an equal and opposite force back on the player's foot, causing the toes to sting.

Front

What are the SI units for force?

Back

The SI units for force are Newtons.

Front

What is Newton's first law of motion?

Back

Newton's first law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an external force.

Front

How does mass affect acceleration according to Newton's second law?

Back

As mass increases, for a given force, acceleration decreases.

Front

What is the relationship between force, mass, and acceleration?

Back

Force is directly proportional to the product of mass and acceleration (F = ma).

Front

What is inertia?

Back

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

Front

What is the formula for calculating gravitational force between two objects?

Back

The formula is F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between the centers of the two objects.
