#5 Calculating Net Forces (Flashcard Grade)

Front

What is Newton's First Law known as?

Back

Inertia

Front

What force pulls objects toward the Earth?

Back

Gravity

Front

What is the definition of resultant force?

Back

The net force acting on an object, taking into account all individual forces.

Front

In a tug of war, if one team pulls with a force of 200N and the other with 150N, what is the resultant force?

Back

50N to the left.

Front

What causes an object to move when a force is applied?

Back

A force is required to change the state of motion of an object.

Front

What is the formula for calculating net force?

Back

Net Force = Total Forces acting in one direction - Total Forces acting in the opposite direction.

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the motion of an object.

Front

What happens to an object in motion when unbalanced forces act on it?

Back

It will accelerate in the direction of the net force.

Front

What is friction?

Back

A force that opposes the motion of an object.

Front

How does mass affect the force required to accelerate an object?

Back

Greater mass requires a greater force to achieve the same acceleration.
