What happens when two forces are in the same direction? |
Their strength is added |
|
|
An object with a greater mass will also have a |
greater inertia. |
|
|
The force of gravity on a person or an object on Earth is called |
Weight |
|
|
The force that one surface exerts on another when the two rub against each other is called |
friction |
|
|
The law of universal gravitation states that any two objects in the universe that have mass |
attract each other. |
|
|
Forces can be added together only if they are |
acting on the same object. |
|
|
According to the law of conservation of momentum, when two objects collide in the absence of outside forces |
the objects momentum will be the same before and after the collision. |
|
|
The overall force on an object after all of the forces are added together |
net force |
|
|
According to Newton's third law of motion, the strength of a reaction force and the action force are |
equal |
|
|
Friction acts in the opposite direction of |
motion.
|
|
|
The force of gravity between you and Earth is greater than the force of gravity between you and anything on the Earth because the Earth has more |
mass. |
|
|
1kg of mass at 1m/s/s equals |
1 Newton |
|
|
When the only force acting on a falling object is gravity, the object is said to be in |
free fall |
|
|
The property of matter that resists change in motion is called |
inertia |
|
|
According to Newton's second law of motion, __________ depends on an object's mass and the net force acting on the object. |
acceleration |
|
|
The two components that affect the gravitational attraction between objects are |
mass and distance |
|
|
Four types of friction are: |
static, sliding, rolling, and fluid |
