What is gravity?

• a force of non attraction

• a force of attraction between objects due to their mass

• a contact force due to the mass

Why is gravity called an attractive force?

• it pulls the objects.

• It pulls and pushes the objects

• it exerts force

Does gravity accelerates all objects at the same rate?

• yes

• no

• yes

• no

Why does gravity accelerates all objects at the same rate?

• because the lighter the object, they fall at the same time.

• because force equals acceleration x mass.

• because the effect of the weight and the one of acceleration cancel each other.

Why is all matter affected by gravity?

• because gravity is everywhere

• gravity is a non contact force

• gravity is a result of mass, so all matter is affected by it.

How does gravity affect planets?

• gravity caused them to have an spherical shape.

• it pushes them together.

• there's a pull that collides them together.

What states the law of universal gravitation?

• All objects repel each other.

• All objects attract each other through gravitational force.

• The more they weight the more they move.
