Newton's Second Law

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.

What happens when unbalanced forces act on an object at rest?

Back

The object begins moving in the direction of the net force.

Front

If two objects have equal forces acting on them, what is this called?

Back

Balanced Forces.

Front

How does mass affect acceleration when the same force is applied?

Back

An object with greater mass will have less acceleration compared to an object with less mass when the same force is applied.

Front

What is the formula to calculate force?

Back

F = m * a (Force equals mass times acceleration).

Front

If a 2 kg object is accelerated at 6 m/s², what force is needed?

Back

12 N.

Front

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

Back

Force is the product of mass and acceleration; increasing mass requires more force to achieve the same acceleration.

Front

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

Back

The object will remain at rest or continue to move at a constant velocity.

Front

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

Back

20 N.

Front

What is an example of unbalanced forces?

Back

A person pushing a stationary car; if the force is greater than the friction, the car will move.
