Bouncy Ball: p = m*v where P is momentum, m is mass, and v is the velocity right before the ball hits the surface. Wiffle Ball: p = m*v where P is momentum, m is mass, and v is the velocity right before the ball hits the surface.

## What causes a ball to bounce physics?

The force of the ball hitting the hard ground puts an equal force back onto the ball, meaning it bounces back up. This happens because balls are made out of an elastic material which allows them to be squashed or stretched and then return to their original shape.

## Is bouncing a ball an example of Newton’s 3rd law?

Bouncy balls are a great example of Newton’s third law of motion. Kids get these toys all the time and loose them but don’t know that every time they bounce it, there is action-reaction forces. The reaction force is when the ball bounces up from the ground or bounces back from the object it was thrown at.

## How high a ball will bounce physics?

Quadratic Model: Height of Single Bounce Using a formula from physics that relates an object’s height to the length of time it has been falling, h = 16t 2 (16 is half the rate of acceleration due to gravity in feet per second squared), it can be determined how long it takes to fall from each height.

## What force acts on a ball?

The forces are the weight, drag, and lift. Lift and drag are actually two components of a single aerodynamic force acting on the ball. Drag acts in a direction opposite to the motion, and lift acts perpendicular to the motion.

## What causes a ball to bounce higher?

When the ball hits the ground, all that kinetic energy has to go somewhere. A lot of it goes back into the ball, giving it more force to pop back up into the airโso the higher the potential energy, the higher the kinetic energy, and the higher the kinetic energy, the higher the bounce!

## Is a bouncing ball elastic or inelastic?

In an elastic collision, not only is momentum is conserved, but also kinetic energy. The total kinetic energy of the system (which includes the objects that collide) is the same before and after the collision. An example of an elastic collision would be a super-bouncy ball.

## What are Newton’s 3 Laws of motion examples?

## What’s Newton’s 3rd law of motion?

Newton’s third law simply states that for every action there is an equal and opposite reaction. So, if object A acts a force upon object B, then object B will exert an opposite yet equal force upon object A.

## What is Newton’s 3rd law and give an example?

Newton’s 3rd law of motion states that action and reaction are always equal but opposite in direction. Common examples of newton’s third law of motion are: A horse pulls a cart, a person walks on the ground, a hammer pushes a nail, magnets attract paper clip.

## How do you calculate bounce force?

- tfall=โ2h/g.
- T=2โ2h/g.
- vb=โ2gh.
- ฮp=2mโ2gh.

## How do you calculate bounce height?

This means we can find the height of bounce one in terms of โ by multiplying the original height by 0.85. Bounce one then must be 0.85 times โ. In a similar way, we can find the height of bounce two by multiplying the height of bounce one by 0.85 again. This can be alternatively written as 0.85 squared times โ.

## How do you calculate height after bounce?

## How do you calculate force to kick a ball?

Substituting in the equation v = s /T gives a value for the initial velocity of the ball. Therefore using Ft = ฮ( mv) the force, F, on the ball can be calculated.

## Is bouncing a ball a balanced force?

No the velocity of the ball is zero but that doesn’t mean that the forces are balanced. After the ball bounces the only force acting on the ball is gravity and this will continue to act throughout the motion of the ball.

## How many forces will act on a ball?

The ball has two forces acting on it. Gravity and the normal force.

## Do heavier balls bounce higher?

The air friction is approximately proportional to the square of the radius at high speeds, and to the radius at low speeds. So for bigger balls the ratio of gravitational to frictional force goes up, compared to small balls. That would tend to make the large balls bounce higher.

## Where does the energy of a bouncing ball go?

Much of the energy of the ball’s downward motion becomes upward motion as the ball returns to its original shape and bounces into the air. The energy in the ball that isn’t converted into motion becomes warmth.

## Which law will determine the quality of bounce?

The moving ball gains kinetic energy when it bounces, and loses potential energy as it falls. Newton’s third law states that every force or action has an equal and opposite reaction.

## How does a bouncy ball have elastic potential energy?

By lifting it up, the ball receives potential energy which is transformed into kinetic energy when you drop it. When the ball hits the ground it gets compressed. It pushes back on the ground and shoots back up into the air. Due to its elasticity it quickly returns to its original shape.

## What is the independent variable in the bouncing ball experiment?

Because we can drop the ball from any height we choose, the drop height is called the independent variable. But since the rebound height depends on the drop height, the rebound height is called the dependent variable.

## Why does a ball bounce lower each time?

The reason it doesn’t bounce higher than where it started is simple: some of the ball’s energy is lost as heat when it bounces, so it doesn’t have as much going up as it did coming down. Knowing that, you might figure that a ball could never bounce higher than the height from which is was dropped.

## What is Newton’s 2nd law called?

The other name for Newton’s second law is the law of force and acceleration.

## What are Newton’s 1st 2nd and 3rd laws of motion with examples?

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
