Mass and energy module 2

All the objects fall with the same acceleration

• True

• False

Suggest the concept of "gravity"

• Galileo Galilei

• Aristotle

The acceleration due to gravity is relatively constant near the Earth’s surface

• True

• False

What is the value of the gravity?

• 9.8m/s2

• -9.8 m/s2

What is the initial position of an object?

• -9.8m/s2

• 0, zero

Maximum value of an object?

• 0, zero

• 10

Free Fall

• the initial velocity of the object is zero. Also, the final velocity and position are going to increase negatively

• an object is launched vertically down, so the initial velocity is negative

• , an object is launched vertically up, so the initial velocity is positive and it will be decreasing little by little until a point where it is zero;

Vertical throw directed downwars

• the initial velocity of the object is zero. Also, the final velocity and position are going to increase negatively

• an object is launched vertically down, so the initial velocity is negative

• , an object is launched vertically up, so the initial velocity is positive and it will be decreasing little by little until a point where it is zero;

Vertical throw directed upwards

• the initial velocity of the object is zero. Also, the final velocity and position are going to increase negatively

• an object is launched vertically down, so the initial velocity is negative

• , an object is launched vertically up, so the initial velocity is positive and it will be decreasing little by little until a point where it is zero;
