Forces and Newton's Laws

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

State Newton's First Law of Motion.

Back

Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by a net external force.

Front

What is the formula for Newton's Second Law of Motion?

Back

The formula is F = m × a, where F is the force applied, m is the mass of the object, and a is the acceleration.

Front

Define acceleration.

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

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

Back

According to Newton's Second Law, the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = m × a).

Front

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.

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance / Time).

Front

What is net force?

Back

Net force is the total force acting on an object after all the individual forces are combined. It determines the object's motion.

Front

What happens to an object in motion when no net force acts on it?

Back

An object in motion will continue to move at a constant velocity if no net force acts on it, according to Newton's First Law.

Front

What is the effect of gravity on falling objects?

Back

Gravity causes all objects to accelerate downwards at approximately 9.81 m/s², regardless of their mass.
