Mo8-L1a: How Does Gravity Affect Forces?
Let’s Begin Key Concept
How Does Gravity Affect Forces?
Types of Forces
What are some contact forces and some
non-contact forces?
A push or a pull is called a force.
An object or a person can apply a force to another
object or person.
What is gravity?
A contact force is a force that is applied when two Gravity is an attractive force that exists between all
objects touch. objects that have mass.
A force that one object can apply to another object
without touching it is a noncontact force.
Gravity and magnetic force are examples of Objects fall to the ground because Earth exerts
noncontact forces. gravity on them.
If mass increase, the force of gravity increases
The force of gravity act between all objects
If distance increases, the force of gravity decreases.
