Accel Forces and Newton's Laws

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size and opposite in direction, resulting in a net force of zero. This means the object will not accelerate.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal in size or opposite in direction, resulting in a net force that is not zero. This causes an object to accelerate.

Front

What is Newton's First Law of Motion?

Back

Newton's First Law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

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 (F=ma).

Front

What is Newton's Third Law of Motion?

Back

Newton's Third Law states that for every action, there is an equal and opposite reaction.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the relationship between mass and acceleration?

Back

According to Newton's Second Law, as mass increases, acceleration decreases for a given force.

Front

What does a free body diagram (FBD) represent?

Back

A free body diagram represents all the forces acting on an object, showing their direction and magnitude.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) can be calculated using the formula a = (final velocity - initial velocity) / time.

Front

What happens to an object if the net force is zero?

Back

If the net force is zero, the object will not accelerate; it will either remain at rest or continue moving at a constant velocity.
