FIZIX1st Sem Review - Forces

Front

What is the net force when all forces acting on an object are balanced?

Back

0 N

Front

State Newton's Second Law of Motion.

Back

Force is equal to mass times acceleration (F=MA).

Front

What does Newton's 1st Law of Motion state?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

Front

Calculate the force applied to a 1200 kg car with an acceleration of 0.5 m/s².

Back

600 N

Front

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

Back

Newton (N)

Front

If a box is experiencing a net force of 20 N to the right, what can be inferred about the forces acting on it?

Back

The forces acting on the box are unbalanced, resulting in a net force.

Front

What is inertia?

Back

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

Front

Describe the relationship between mass and acceleration in Newton's Second Law.

Back

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

Front

What is the formula to calculate net force?

Back

Net Force = Mass x Acceleration (F = m*a)

Front

What is an example of Newton's 3rd Law of Motion?

Back

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