What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula: F = ma (Force = mass × acceleration).

Front

What is a Balanced Force?

Back

Balanced forces occur when two objects exert equal force on each other, resulting in no change in motion.

Front

What is the formula to calculate acceleration?

Back

Acceleration can be calculated using the formula: a = F/m (acceleration = force/mass).

Front

If a force of 20 N is applied to a mass of 5 kg, what is the acceleration?

Back

4 m/s².

Front

What happens to the acceleration of an object if the mass increases while the force remains constant?

Back

The acceleration decreases because acceleration is inversely proportional to mass.

Front

What is the acceleration of an object traveling at a constant velocity?

Back

0 m/s².

Front

Why would one ball accelerate more than the other when pushed with the same amount of force?

Back

Different masses affect the acceleration; the ball with less mass will accelerate more.

Front

If Football A has a greater mass than Football B, which will have greater acceleration when both are thrown with the same force?

Back

Football B will have greater acceleration.

Front

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

Back

Force is equal to mass multiplied by acceleration (F = ma).

Front

What is inertia?

Back

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