Force Facts
What is a force?
A push or a pull that can change an object's motion.
Is kicking a soccer ball a push or a pull?
Push
What is gravity?
A force that pulls objects toward Earth.
What is friction?
A force that slows down motion when two surfaces rub together.
What does speed describe?
How fast something moves
What is motion?
The movement of an object from one place to another.
Pulling a wagon toward you is an example of what type of force?
Pull
Why does a dropped pencil fall to the ground?
Gravity pulls it down
Which surface creates more friction: ice or carpet?
Carpet.
If a bike travels farther in the same amount of time, is it moving faster or slower?
Faster
What are the two main types of forces?
Push and Pull
Opening a door by pushing it away from you uses what force?
Push
Does gravity push or pull objects?
Pull
Why does a toy car slow down on carpet?
Friction between the car and carpet slows it down.
What is a pattern?
Something that repeats or can be noticed in observations.
What happens when a force acts on an object?
It can make the object start moving, stop moving, speed up, slow down, or change direction.
A child pushes a toy car harder. What might happen?
The car may move faster or farther.
How does gravity affect a skateboard going downhill?
Gravity pulls the skateboard downward and helps it move faster.
How can friction be helpful?
It helps us walk, stop cars, and hold objects.
A balloon rocket moves farther when it has more air inside. What is the cause?
More air creates a stronger force.
A scientist wants to learn why a toy car moves differently on different surfaces. What should they do?
Investigate and collect evidence by testing different surfaces.
Why does a stronger push usually make an object move differently?
A stronger force can cause a bigger change in motion.
What would happen without gravity?
Objects and people would float instead of staying on the ground.
A skateboard rolls farther on smooth pavement than grass. Why?
Grass has more friction and slows the skateboard down.
In an investigation, students test how different surfaces affect a toy car. What is the effect they observe?
How far or how fast the car moves.
