What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma).

How do you calculate force using mass and acceleration?

Back

Force can be calculated using the formula F = ma, where F is force, m is mass, and a is acceleration.

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

Back

The unit of force in the SI system is the Newton (N).

What does Newton's Third Law of Motion state?

Back

Newton's Third Law states that for every action, there is an equal and opposite reaction.

What is the relationship between mass and acceleration in Newton's Second Law?

Back

In Newton's Second Law, mass and acceleration are inversely related; as mass increases, acceleration decreases for a given force.

What is friction?

Back

Friction is the force that opposes the relative motion of two surfaces in contact.

Front

How does friction affect motion?

Back

Friction opposes motion, making it harder for objects to start moving or to keep moving.

What is the formula to calculate mass using force and acceleration?

Back

Mass can be calculated using the formula m = F/a, where m is mass, F is force, and a is acceleration.

Front

What is the significance of unbalanced forces?

Back

Unbalanced forces result in a change in the motion of an object, causing it to accelerate.

What is the effect of a net force of zero on an object's motion?

Back

If the net force on an object is zero, the object will remain at rest or continue to move at a constant velocity.
