Force
What is a force?
Force is a push or a pull that causes an object to change speed, direction, or to change size or shape.
What is Net Force?
Net Force is the combination of all forces acting on a object.
What are Balanced forces?
When the forces on both sides are the same
What is a Unbalanced mean?
When both sides are not even.
What is Newton's 1st Law?
An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.
What is change in speed called?
Acceleration
True or False:
The measurement in Newtons
True: All forces are measured in Newtons
True or False:
The forces can sometimes cancel each other out?
False:
They always cancel each other out and there will be no movement.
True or False:
When a man is pulling a plane and it is moving, is unbalanced?
True:
Because the man is moving the plane and if it wasn't moving it would be balanced.
If a ball is moving and not speeding up what does that mean?
It means that it is moving at a constant speed which Newton's 1st Law says "An object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force."
What is an example of a change in direction?
Kicking a soccer ball as it is coming at you
What do you do if the forces acting on an object are in the same direction?
You add together to form the net forces
If there is no change in direction or speed, is it balanced?
Yes:
Because it doesn't move and that means it's a balanced force.
What is an example of Unbalanced force?
In a game of tug-o-war one side has 10 people and the other side has 2 people.
If there is no net force acting on the object, what will happen to the object?
the object will maintain a constant velocity.
What is an example of change in shape or size?
Pushing or pulling on a spring
When someone is pulling on the same side, is it there net force?
Yes: Because the definition is Net Force is the combination of all forces acting on a object.
Is the Net force zero?
Yes: Because there is no movement
Is there Unbalanced force when a person has more stregnth than the other side?
Yes: Because the forces aren't even.
When a object has more mass, does it have more Inertia?
It has more Inertia becasue it need a larger Net force.
What is force measured in?
Newtons
What do you do if there in oppiste direction?
You have to subtract the smaller force from the bigger force.
Is the Net force in a balanced situation zero newtons or more than that.
Zero: Because The objects aren't moving and each side are even.
Is the connection between the Moon and the Earth is a unbalanced force or a balanced force?
An unbalanced force because the Moon changes direction.
What is Inertia?
An object to resist any change in its state of motion or rest.
