What happens if I throw a ball up in a moving car?

When a person throws a ball up in a moving vehicle, say, a train, the ball does come straight back to thrower as though the train were at rest. This is an iron-clad evidence for the law of inertia as the horizontal motion of ball before, during and after the catch is the same.

What is the physics behind throwing a ball?

The study of how projectiles move through the air is called projectile motion. When a projectile is launched, it has an initial velocity (its speed and direction of motion). When a projectile is moving through the air, however, it is subject to the force of gravity, which causes it to move down toward Earth.

What forces are acting when you throw a ball?

So on any thrown ball, we’ve got gravity pulling it down; the drag force, which is basically air resistance, slowing the ball as it moves forward; and the Magnus Force, which curves the ball away from its principal flight path depending on its spin.

What is the motion of a thrown ball?

Projectile motion is motion under the influence of gravity. If we stand at the edge of the roof of the Science Building and throw a ball up at an angle, it moves up and then down vertically while it moves horizontally. This is projectile motion.

What is the science behind throwing a football?

Can you describe the projectile motion?

Projectile motion is the motion of an object projected vertically upward into the air and moving under the influence of gravity. Projectile motion is the motion of an object projected horizontally into the air and moving independently of gravity.

When a ball is thrown inside a moving bus?

As known that the kinetic energy of a body is directly proportional to the square of the velocity of the body. so, when the ball is thrown inside the bus, its velocity gets added up with the velocity of the bus. Therefore, its kinetic energy depends on the velocity of the bus.

Why does the ball come right back in hand when thrown upwards in a moving train and behave as if the train is at rest?

Due to inertia of motion, as long as the ball stays in air, both the person and the ball move in the same direction which cause the ball to fall back to the thrower’s hand.

Why does a ball not move in a moving car?

When you tossed the ball inside the car, its initial speed was 100mph, like of all other objects including you and your hand which was holding the ball. Since no force is applied to the ball, it’ll keep moving at this speed. It’s called inertia.

Is throwing a ball potential energy?

When you finally throw it, this kinetic energy is converted to potential energy(of the ball) as the ball moves up in the air. Note:Potential energy is not equal to kinetic energy, at least not always.

How is Newton’s first law used in baseball?

Newton’s first law of motion states than an object at rest will stay at rest and an object in motion will stay in motion unless acted on by an external force. At the most basic level, the baseball would simply stay on the ground forever, until the pitcher applied a force to pick it up.

What force is doing work on the ball as it falls?

Bookmark this question. Show activity on this post. I have studied today that if a ball was to fall a certain height, then the work done by gravity on the ball would equal the work done by the ball’s equal and opposite gravitational pull. By W=Fd, this means that the earth must travel the same distance as the ball.

What is the acceleration when you throw a ball up?

The ball’s acceleration is the same throughout the throw (It is 9.8 m/s2 toward the earth). The direction of the ball’s motion is upward, and doesn’t change. The speed of the ball will decrease as it goes higher.

What happens to velocity and acceleration when a ball is thrown up?

For example, when a ball is thrown up in the air, the ball’s velocity is initially upward. Since gravity pulls the object toward the earth with a constant acceleration g, the magnitude of velocity decreases as the ball approaches maximum height.

What is the acceleration when a ball is thrown in the air?

The cause of the ball’s acceleration is gravity. The entire time the ball is in the air, its acceleration is 9.8 m/s2 down provided this occurs on the surface of the Earth. Note that the acceleration can be either 9.8 m/s2 or -9.8 m/s2.

How is physics used in soccer?

Physics Behind Soccer Ball Curving or Spinning The curving, spinning, or bending is caused by a force referred to as Magnus Effect which is generated as air waves move over the spinning ball. As the air flows over the surface of the ball, a thin boundary layer of air is created and clings the surface.

How is friction used in football?

Friction in Football In football, frictional forces oppose the movement of the ball when it is rolling or sliding during the play. This is due to the fact that these balls move against the surface of the ground generating a resisting force (surface friction) which considerably slows down the ball.

Is catching a ball a push or pull?

A pull is a force to move something towards us. Kicking a ball is a push since the ball moves away from us.

Which is an example of projectile motion?

you throw the ball straight upward, or you kick a ball and give it a speed at an angle to the horizontal or you just drop things and make them free fall; all these are examples of projectile motion. In projectile motion, gravity is the only force acting on the object.

What are the 3 types of projectile motion?

  • Oblique projectile motion.
  • Horizontal projectile motion.
  • Projectile motion on an inclined plane.

What are some examples of projectile motion in everyday life?

  • Firing a Canon.
  • Throwing a Basketball in the Basket.
  • Sneezing.
  • Javelin Throw.
  • Archery.
  • Water Escaping a Hose.
  • Car and Bike Stunts.
  • Golf Ball.

When a ball is thrown inside a moving bus does its kinetic energy depends on the speed of bus explain?

Hi Shivani, Yes, the KE of the ball thrown inside the bus is dependent on the speed of the moving bus. Consider the bus is moving with the speed 40 km/h. A boy playing outside the bus throws a ball towards another person sitting inside the bus with speed 50 km/h in the same direction as that of the bus.

When a ball is thrown vertically upwards?

The acceleration due to gravity acts downwards towards the earth surface and hence, as ball is thrown vertically upward direction which is opposite of acceleration due to gravity.

Why does a ball thrown upward in a train moving with uniform velocity returns to the thrower?

The ball gains the same horizontal velocity as that of the train. Hence, it moves the same distance as the train in the horizontal direction and it falls back to the thrower’s hand.

Which of the following statements is wrong about a ball thrown vertically up?

Expert-verified answer ” It is moving with constant acceleration “.
