Big Idea 13 Force

What is the definition of force?

• A push or a pull on an object.

• The energy stored in an object.

• The speed of an object in motion.

• The resistance of an object to change its state.

The difference between a push and a pull is:

• A push involves applying force away from oneself, while a pull involves applying force towards oneself.

• A push involves applying force towards oneself, while a pull involves applying force away from oneself.

• A push and a pull are the same, involving no force.

• A push involves no force, while a pull involves force.

A push is:

• a force that moves an object away from the source

• a type of pull

• a stationary object

• a type of friction

Give an example of something you can push.

• A door

• A button

• A swing

• A car

What is the force that causes an object towards the force?

• Pull

• Push

• Gravity

• Friction

Give an example of something you can pull.

• A rope

• A car

• A house

• A tree

What will happen to an object when balanced forces are applied to it?

• The object will start moving.

• The object will stop moving.

• The object will change direction.

• The object will remain in its current state.

What will happen to an object when unbalanced forces are applied to it?

• The object will remain stationary.

• The object will move in the direction of the net force.

• The object will move in the opposite direction of the net force.

• The object will explode.

The effect of friction on a moving object is to:

• increase its speed

• decrease its speed

• have no effect

• change its direction

A spring scale is used to measure:

• Temperature

• Length

• Weight

• Volume
