# How do you change the direction of a rolling ball?

## How do you change the direction of a rolling ball?

Explanation: If a rolling ball hits another ball they will change directions or speeds based on the force applied. When we push the balls into each other their force is redirected.

## What causes the ball to change the direction of the movement?

Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity.

How does the angle affect how far the ball goes?

In most cases you should see that a medium, 45-degree angle made the ball go the farthest. When you throw the ball at a very shallow angle, gravity pulls it down and the ground is closer, which ends the throw sooner so it does not have as much time to travel as far forward.

What happens to the ball when it is pushed in the direction of the motion?

The applied force makes the ball move towards the goal. If the force applied on the object is in the direction of its motion, the speed of the object increases. If the force is applied in the direction opposite to the direction of motion, then it results in a decrease in the speed of the object.

### How would you change the direction of a moving object?

A force can speed up or slow down an object. A force can change the direction in which an object is moving. A bigger force on an object will produce a bigger change in the motion.

### How does the angle affect projectile motion?

Higher launch angles have greater times in the air The time in air is determined by the initial vertical velocity. Since steeper launch angles have a larger vertical velocity component, increasing the launch angle increases the time in air.

What angle is best for distance?

45 degrees
A projectile, in other words, travels the farthest when it is launched at an angle of 45 degrees.

What happens when the ball is pushed?

In flight, the ball rotates about the center of gravity. Newton’s laws of motion describe the translation of the center of gravity. As the ball moves through the air, the air resists the motion of the ball and the resistance force is called drag.

## How do you change the direction of a ball without changing speed?

By applying force on the object. Force changes the direction of motion of the object. For example : a soccer player control the motion of a soccer ball by applying a force. It will change the ball’s direction not its speed.

## How does changing the launch angle affect the distance traveled by a projectile?

Launching slightly upward will increase the distance because the projectile travels for a longer time. But launching too close to straight up would decrease the distance, since the projectile has no horizontal velocity.

Which launch angle causes the ball to travel further horizontally before hitting the ground?

In that case, the ball will travel the maximum horizontal distance before landing if it is launched at an angle of around 10 or 20 degrees to the horizontal.

Why hit the ball with a high angle?

Explain hit the ball with a high angle bc it will carry more in the air and trajectory/projection will carry it further; less friction carrying the ball Golf drives travel much farther than Major League home runs. Why might this be?

### What happens to the velocity of the ball during upward movement?

In other words, during upward movement, the ball is moving with retardation. And finally, the velocity of the ball becomes zero at a height. Then again it starts falling downwards vertically and this time its velocity increases gradually under the influence of gravity.

### What direction should the cue ball move when you hit it?

For a stun shot, most people know the right answer: in the tangent line direction, perpendicular to the OB direction. This is the 90° rule. For a rolling CB, the cue ball changes direction by about 30° for a wide range of cut shots (1/4 to 3/4 ball hit). This is the 30° rule.

What is the time it takes a ball to hit the ground?

REASON: The x motion is independent of the y motion for projectiles. So the time t=1.75 s for the ball to hit the ground is the same both in this case where the ball moves horizontally and the case of the ball falling straight down.
