Forces and their effect on Objects

Force is...

• the direction of the movement of an object

• the movement of an object between two points

• a push or a pull resulting in the interaction of two objects

An example of a contact force is when...

• you move a box with your hands

• an apple falls from a tree to the floor

• metal is attracted by a magnet

An example of a non-contact force is when...

• you pull the door to open it

• an apple falls from a tree to the floor

• someone pushes you at the swing

An example of magnetism is when...

• a girl swinging at the park

• a cellphone falls into a pool

• a nail is attracted by an object

There is no gravity...

• in space

• in the ocean

• in the air/atmosphere

Friction is a force that acts...

• in neither direction of the motion of the object

• in the same direction of the motion of the object

• opposite to the direction of the motion of the object

Which object has more inertia? (so, need more force to move)

• Car

• Truck

• Skateboard

An increase in an object's speed is called:

• reaction

• inertia

• acceleration

When you are playing on the slide, what force tries to stop you?

• friction

• gravity

• magnetism

The force that acts towards the center of the Earth is called...

• magnetism

• gravity

• friction
