If a 5 kg block has an acceleration of 2 m/s², what is the net force acting on it?

Back

10 N (using F = ma, where F = 5 kg * 2 m/s²).

What is the term for the force that opposes the motion of an object?

Back

Frictional force.

Front

What is the force that supports an object resting on a surface?

Back

Support force.

Front

If two forces of 10 N and 10 N act in opposite directions, what is the net force?

Back

0 N (they cancel each other out).

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

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

Back

Greater mass results in less acceleration for the same applied force.

Front

What happens to the acceleration of an object if the net force acting on it is doubled?

Back

The acceleration doubles (F = ma).
