While rollerblading, a cat jumps from a tree and lands in front of you. You use your brakes and you come to a sliding stop. Which force greatly increases when you use your brakes and slide?
push
pull
friction
gravity
Where is the friction as the greyhounds run?
There is friction between the greyhounds and the dirt.
There is friction between the air and the dirt.
There is friction between the dirt particles.
There is friction between the greyhound's paws and tail.
To make an object travel a very short distance, what size force should be applied to the object?
medium
small
strong
weak
If there were no friction, what would happen to the girl after she slides down the slide and hits the ground?
The girl would stop once she hits the ground.
The girl would stop instantly.
The girl will slide for a few minutes, but then she would stop sliding.
The girl would keep sliding even after she hit the ground.
Julian is playing golf. He predicts he can make the ball move a longer or shorter distance depending on the force he applies. Which of the following conclusions matches his prediction?
The force applied to the ball has little effect on the distance it travels.
The force of motion is different when a strong or a weak force is applied to the ball.
When a strong force is applied to the ball, the ball will travel a shorter distance.
When a weak force is applied to the ball, the ball will travel a longer distance.
Watch Norm Duke roll his bowling ball. Which statement describes the force of motion when hitting an air hockey puck?
When Norm uses a strong force to roll the ball, there is a smaller change in motion.
When Norm uses a weak force to roll the ball, there is a greater change in motion.
A strong force and a weak force result in the same change in motion.
When a stronger force is applied to the object, the change in motion is greater.
Our class made catapults to launch objects. We conducted an experiment to see which object traveled the longer distance. What did we need to do to properly conduct our experiment?
Apply the same force of motion when we launched each object.
Apply different forces of motion when we launched each object.
Launch one object into the wind and another object against the wind.
Use the force of the wind to decide which object will travel farther.
When an equal force is applied to each of the objects in the image, which object will have the greatest change in motion?
2 kg
5 kg
10 kg
20 kg
If you were to apply an equal push force to two objects, one with a small mass, and one with a large mass, what would most likely be the outcome?
The smaller object will have a greater change in motion.
The larger object will have a greater change in motion.
Both objects will have an equal change in motion.
Neither object will have a change in motion.
Olivia is having a hard time pulling her wagon. What would she need to do to decrease the amount of force needed to pull the wagon easier?
Olivia could add objects to the wagon to increase the mass, so she could decrease the force.
Olivia could remove objects to decrease the mass of the wagon, so she wouldn't have to use so much force.
Olivia could decrease the amount of friction between the wagon and the floor.
Olivia could remove objects to increase the amount of friction between the wagon and the floor.
Watch the cute dog, pushing the other dog in the cart. Which statement describes the change in motion if the mass of the cart were changed?
If the mass of the cart decreased, the force needed would decrease.
If the mass of the chair increased, the force needed would decrease.
If the mass of the chair decreased, an increased force would not move it.
To keep the motion, the force needed would stay the same when the mass of the chair is changed.
What type of evidence is gathering information through your senses or using scientific tools?
predictions
results
scientific research
observations
Dylan is observing the force needed to make an object move faster. He follows a procedure and records the mass of the objects. What would verify that the results of the investigation are accurate?
He can repeat the experiment procedure and get very different results.
He can do a different experiment procedure using different objects.
He can repeat the experiment procedure and get similar results.
He can observe different objects in motion outside on a walk.
