Investigating Forces
What do we call the push or pull that can change an object's motion?
What is force?
If two cars travel the same distance but one takes longer, which car is faster?
What is the car that took less time?
What is gravity?
What is the force that pulls objects toward the center of the Earth?
If you push a toy car, what happens to its speed?
What is it increases?
How can you find out which object is slower if they travel the same distance?
What is the object that takes more time?
How does gravity affect a ball when you throw it up?
What is it slows down, stops, and then comes back down?
What happens to an object's direction when you apply force to it?
What is it changes direction?
If a bicycle takes 10 minutes to go 1 mile and a runner takes 5 minutes, who is faster?
What is the runner?
What would happen to a feather and a heavy rock if you drop them at the same time?
What is they would fall at the same rate in a place without air resistance?
If you drop a ball and it rolls down a hill, what force is acting on it?
What is gravity?
Why is it important to compare the time it takes for objects to travel the same distance?
What is to find out which one is faster or slower?
How does gravity keep us on the ground?
What is it pulls us toward Earth and stops us from floating away?
How can you change the direction of a toy car on a flat surface using a force?
What is push it from a different direction or use an obstacle to change its path?
If you see two trains leaving the station at the same time, how can you tell which one is going faster?
What is the train that gets farther ahead in the same amount of time?
Why do astronauts feel weightless in space even though gravity is still acting on them?
What is because they are in free fall, moving around the Earth at the same speed as their spaceship?
