Front

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 x acceleration).

Front

How does mass affect acceleration when force is constant?

Back

If the mass of an object increases while the force applied remains constant, the acceleration of the object decreases.

Front

What is the relationship between force and acceleration?

Back

Force and acceleration are directly related; as force increases, acceleration increases, provided mass remains constant.

Front

What is the formula to calculate force?

Back

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

Front

What happens to acceleration if the net force increases while mass stays the same?

Back

Acceleration increases.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the total forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

Front

What is an example of balanced forces?

Back

Balanced forces occur when two equal forces act in opposite directions on an object, resulting in no change in motion, such as a book resting on a table.

Front

How do you calculate the force exerted on an object?

Back

Force can be calculated by multiplying the mass of the object by its acceleration (F = ma).

Front

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

Back

The unit of force is the Newton (N).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, typically measured in meters per second squared (m/s²).
