## How does a bowling ball move?

The bowling ball hits the break point and straightens out heading towards the pocket. Once the bowling ball makes its motion towards the pocket, it eventually runs out of energy and it is rolling at its slowest speed with the least amount of axis rotation. The bowling ball needs to be in a roll when it hits the pins.

## How fast must a projectile moving horizontally travel so that the curve it follows matches the curve of Earth?

how fast must a projectile moving horizontally travel so that the curve it follows matches the curve of earth? about 8 km/s if it is close to earth.

## What is a projectile that continually falls around Earth?

A satellite is often thought of as being a projectile which is orbiting the Earth. satellite is a projectile.

## Why is velocity a vector quizlet?

Why is speed classified as a scalar quantity and velocity classified as a vector quantity? Speed has no particular direction; velocity specifies direction. You just studied 18 terms!

## What would happen if a bowling ball collides with a standing pin?

When the bowling ball collides with the pins, the momentum the ball loses is equal to the momentum the pins gain. An object’s inertia resists changes its motion. The momentum and force of a rolling ball is greater than that of the pins. This inertia of the ball will knock down the pins.

## What causes a bowling ball to hook?

The proper bowling swing is on a straight plane, like a pendulum. The hook is caused by a combination of two forces, side rotation and revolution. These are the result of the way you release and rotate your fingers, not any movement from your wrist!

## Will a vector at 45 degrees to the horizontal be larger?

Velocity is a vector quantity because it has a direction in space. The resultant of two vectors is the diagonal of the rectangle that starts where the two vectors start. The horizontal and vertical components of a vector that is at 45o to the horizontal will be shorter than the vector itself (so the vector is larger).

## At what angle should the Slingshot be aimed to achieve its maximum range?

Explanation: This type of motion is called projectile motion. So Hmax is attained when sin2θ is maximum. So θ=90∘.

## What keeps a satellite up in its orbit?

Even when satellites are thousands of miles away, Earth’s gravity still tugs on them. Gravity–combined with the satellite’s momentum from its launch into space–cause the satellite go into orbit above Earth, instead of falling back down to the ground.

## What force continually changes a satellite’s direction?

Explain why a satellite in orbit around Earth does not fall into Earth. because of inertia, it continues to accelerate, and because of gravity, it constantly changes direction, therefore falls around the Earth instead of into it.

## What is the acceleration of a satellite in orbit?

A satellite in a circular orbit accelerates toward the object it is orbiting at a rate equal to the acceleration of gravity at its orbital radius. As in a falling elevator, objects in orbit are in constant freefall. Objects in free fall have no normal force acting upon them, and thus no weight.

## What force does the Earth exert on the satellite?

As a satellite moves around the Earth in a circular orbit, the direction of the force of gravity is always towards the centre of the Earth.

## Why is speed classified as a scalar and velocity a vector?

Why is speed classified as a scalar quantity and velocity classified as a vector quantity? Speed here does not have any specific direction and have only magnitude so is a scalar quantity. Velocity is a vector quantity which can be specified both in the magnitude and direction.

## What is a temperature group of answer choices vector scalar?

Temperature is a scalar quantity. A measurement of temperature has magnitude, but gives no information about direction. Energy is a scalar quantity.
