Newton's Second Law of Motion

Front

What does Newton's Second Law of Motion state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

How does increasing the force applied to an object affect its acceleration?

Back

Increasing the force applied to an object results in greater acceleration.

Front

If a ball is rolling and a force is applied in the same direction, what happens to the ball's speed?

Back

The ball's speed increases.

Front

What is the formula to calculate force according to Newton's Second Law?

Back

F = ma, where F is force, m is mass, and a is acceleration.

Front

How much force is required to accelerate a 2 kg object at 6 m/s²?

Back

12 N (calculated using F=ma).

Front

What is the force required to accelerate a 10 kg object upward at 2 m/s²?

Back

20 N (calculated using F=ma).

Front

If two objects are thrown with the same force, how does mass affect their acceleration?

Back

The object with greater mass will have less acceleration, while the object with less mass will have greater acceleration.

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

As mass increases, acceleration decreases if the force remains constant.

Front

What happens to the acceleration of an object if the mass is doubled while the force remains the same?

Back

The acceleration is halved.

Front

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

Back

The unit of force is the Newton (N).
