Explain why the amount of friction would be different on an icy surface and a dry,concrete surface.How does the amount of friction affect the movement of an object across both surface?

Icy surface would have less friction than the concrete surface. on icyAn object would move faster and travel fart0omher

We can say that the force can set a stationary object into motion. True or False

True

Explain the effects of a force acting on an unmoving object?

When you apply force such as push or pull on an unmoving object, it cause the object to move.

How can you increase friction?

Rough or sticky materials to increase friction.

When have you experienced unbalanced forces?

Playing See-saw

Explain a time that you experienced little friction.

Sliding

The ball is rolling. If we place the cover of notebook at a slight angle in the path of rolling ball,the ball’s direction will not change. True or False

False

An egg is about to roll off the counter. How can you get the egg to stop without picking it up?

Block with opsticle

Forces can change of the object’s motion. true or false

true

What types of surfaces typically have least friction between them?

Smooth or slippery surface

What action could cause an object to move forward?

Push force

What is friction?

A force that occurs when one object rub against another.

Place the baseball on a table and if you push it a little bit, it will roll forward quickly. True or False

False

How could you explain the difference in the effect of a balanced and unbalaned force on an object?

Balanced forces do not cause a change in motion but unbalanced does.

How is friction helpful?

It helps breaks stop a bike, it helps shoes push off the floor to walk.

If we push the ball harder, we are applying less force. True or False

False

In what ways can motion be changed by a force?

Motion can change in speed or direction.

Force is define as a push only. True or False

False

Our baseball that is on the table is now rolling . If we place our hand infront of it the ball will stop. True or False

True

How is an object’s motion change?

A force is applied to it.
