Is throwing a ball balanced or unbalanced?

Is throwing a ball balanced or unbalanced?

When you throw a ball, you need to apply a force. When the forces acting on an object are equal, but in opposite directions we say that they are balanced. When these two forces equal out, the object is at equilibrium. Every stationary is in equilibrium.

Is hitting a ball an unbalanced force?

The applied (unbalanced) force has caused the ball to accelerate off the ground. Once in flight the only unbalanced forces acting are gravity and air resistance. Gravity causes the ball to accelerate downwards throughout its flight. The force of gravity is in balance with a normal force.

How is a ball an unbalanced force?

The soccer ball is already moving when it is passed from one player to another. When the ball reaches the second player, the player exerts an unbalanced force – a kick – on the ball. After the kick, the ball moves in a new direction and with a new speed. A kick on the ball creates a new direction and speed on the ball.

Is a ball rolling down a hill balanced or unbalanced?

Answer: An unbalanced force refers to the force that causes change in velocity that is causes acceleration of the body. An unbalanced force makes a body to change either its speed or direction or both. A ball rolling down a hill, accelerates downwards because of gravitational force.

How does air flow around a balancing ball?

Air rushes in an arc around the top of the ball and then continues outward above the ball. This outward-flowing air exerts an inward force on the ball, just like the downward flow of air beneath a helicopter exerts an upward force on the blades of the helicopter. This explanation is based on Newton’s law of action and reaction.

How can you feel the force of a balancing ball?

Suspend a ball in a stream of air. A ball stably levitated on an invisible stream of air is a dramatic sight. Try to pull the ball out of the air stream—you can feel a force pulling it back in. You can also feel that the air stream is being deflected by the ball. This activity shows the force that gives airplanes lift.

What happens when you throw a tennis ball into the air?

There is an instant during the throwing of the ball, as the upward force from the hand is decreasing, but before the ball’s release, at which the upward force from the hand and the downward force from gravity are in precise balance. At that instant, the acceleration is zero, even though velocity is at its peak.

How does a juggler throw a ball into the air?

Acceleration is present on any body that has an unbalanced force acting on it. As the student starts moving his hand upward to throw the ball, the ball has an upward force from the hand that is greater than the downward force from gravity. The ball therefore accelerates upward.
