Force and Motion | Science for Kids

What is force?

• a push or pull that can cause an object to move or change direction

• the energy of a moving object

Explain how a doorknob is an example of force. 

What is motion?

• the push of pull of an object

• the movement of an object from one place to another 

What is speed?

• the change in direction of an object

• the push of pull of an object

• how fast an object is moving

What tools would you use to calculate an objects speed?

• stopwatch and pan balance

• measuring tape and thermometer

• stopwatch and measuring tape

• ruler and spring scale

What is gravity?

• the push or pull of an object

• how fast an object is moving

• the force that pulls objects towards earth

If friction is the force that opposes motion when two surfaces rub against each other, which of the following would be an example of friction?

• letting a balloon go 

• car tires rubbing against the road when you hit your breaks

• dropping different objects and seeing which one hits the ground the fastest

Friction causes ___________.

• heat

• objects to cool

True or False

Force cannot cause objects to slow down or speed up. 

• True

• False

Newton's first law of motions states.... 

• an object in motion will stay in motion unless acted upon by another force.

• an object at rest will stay at rest unless acted upon by another force.

• both of the above are apart of Newton's first law of motion
