Unform Acceleration

As the inclined plane becomes steeper, the acceleration of the rolling ball

The maximum acceleration of the rolling ball was reached when the inclined plane was positioned _______ as if the ball is falling.

Falling objects have the same acceleration when there is no ___.

When these balls are thrown from the same height and in a vacuum, they will fall at the same acceleration regardless of their ______.

As the inclined plane becomes steeper, the acceleration of the rolling ball _________.

What is Galileo's concept of falling objects on his experimentation?

• Object falling with changing acceleration.

• Object falling with changing direction.

• Object falling with uniform acceleration.

• Object falling with speed.

As Galileo changed the angle of inclination of the planes he used, what happened to the value of the acceleration of the rolling ball?

• The acceleration of the rolling ball became zero as the steepness of the plane was increased.

• The acceleration of the rolling ball decerased as the steepness of the plane was increased.

• The acceleration of the rolling ball stayed the same as the steepness of the plane was increased.

• The acceleration of the rolling ball increased as the steepness of the plane was increased.

At what position of the inclined plane did Galileo find the greatest acceleration of the rolling ball?

• When the plane is inclined at 90 degrees.

• When the plane is inclined at 60 degrees.

• When the plane is inclined at 45 degrees.

• When the plane is inclined at 30 degrees.

What material did Galileo use to study the acceleration of the falling body?

• Balls

• Horizontal Plane

• Inclined Plane

• Rings

What causes the object in vacuum fall at the same time?

• Air resistance

• No air resistance

• Air in space

• Mass of an object
