Pull

True or false: Playing tug of war is a type of contact force.
True: When you pull on the rope in a game of tug of war, you're using a contact force. Your hands have to touch the rope to pull it.

Is this an example of tension?
Yes

Is this an example of Inertia?
A roller coaster at a theme park uses inertia to keep the cars moving along the tracks.

True or false: An apple falling from a tree is a contact force.
False. You did nothing to make the apple fall. It fell on it's own and you did not touch it, therefore it is not an example of contact force.

True or false: Friction happens when two surfaces rub against each other
True

True or false: Is this an example of Inertia?
True. A person trying to push a heavy object, they have to overcome the inertia of the objects to make it move.

True or false: Pulling a wagon is a type of contact force.
True. If you pull a wagon full of toys, you're using a contact force. Your hand pulls the handle of the wagon to make it move.

True or false: Friction always makes an object move faster.
False
300
True or false: Tension only works when something is pulling an object.
True

Is this a spring force?
No it isn't.

Is this an example of a push or a pull?
Push

True or false: Throwing a ball is an applied force.
True. You have to hold the ball in order to throw it.

What is tension?
Tension is a type of contact force. It happens when you pull on a string, a rope, or anything else that's stretchy.
400
True or false: Tension is a pushing force
False. Tension is a pulling force.

Is this an example of a spring force?
Yes it is.

What is the definition of a force?
A force is any push or pull that causes an object to move.
500
What is a contact force?
Contact forces are the pushes or pulls that happen when two things tough each other. (Example: You are pushing a toy car. Your hand is applying a force to the car - therefore it is a contact force).
500
What is frictional force?
Frictional force that makes it harder to slide objects across each other. For example if you tried to slide a box on ice, there isn't much friction to slow the box down.
500
What is inertia?
Inertia means an object wants to keep doing what it's already doing. For example, if a toy car is rolling on the floor, it wants to keep rolling.

What is spring force?
A Spring force is the force made by a compressed or stretched spring upon any object that is attached to it.
