A female gymnast weighs 200 N. If she is hanging stationary from a high bar,how many forces are acting on her?
A. one
B.five
C.four
D.two
E.three
WOuld it be choice A or D?
gravity down
tension on arms from bar up
2
net of zero therefore does not accelerate
a body with only one force acting on it must accelerate
To determine how many forces are acting on the female gymnast hanging stationary from a high bar, we need to consider the different forces acting on her.
1. Gravitational force (weight): The female gymnast weighs 200 N, and this weight is acting downward due to gravity.
2. Tension force: The high bar exerts an upward force on the gymnast to support her weight. This force is called the tension force.
So, the answer is D. There are two forces acting on the female gymnast hanging from a high bar - the gravitational force (weight) acting downwards and the tension force acting upwards.
