A boy rides a skateboard. Which statement best describes how his energy changes as he moves?
Potential energy increases from point X to point Y and kinetic energy decreases from point Y to point Z.
Potential energy decreases from point X to point Y and kinetic energy decreases from point Y to point Z.
Kinetic energy of his motion from point X to point Y is converted to a force that moves him up the hill to point Z
Potential energy of his motion from point X to point Y is converted to a force that moves him up the hill to point Z
According to Newton's Third Law of Motion, when a hammer strikes and exerts a force on a nail, the nail...
creates a friction with the hammer
disappears into the wood
exerts an equal force back on the hammer
moves at a constant speed
Caitlyn, Corona, and Inyoung take turns hitting a ball with the same bat. At the moments that they hit the balls, their bats are swinging at different speeds. Whose bat hits the ball with the most force?
Caitlyn, whose bat is speeding up at the moment it hits the ball.
Corona, whose bat is slowing down at the moment it hits the ball.
Inyoung, whose bat is swinging at a steady speed at the moment it hits the ball.
All three will hit the ball with the same amount of force.
Priyanka held two magnets together and noticed a force between them. This force surrounding a magnet is known as the magnetic
surface
surrounding
field
The closer you are to the magnet the
weaker
stronger
Claire threw the ball and it hit her mother's vase. Energy transferred from the moving ball to the stationary vase, causing the vase to knock over. This is an example of Energy Transfer. Which laws can also be used to describe these actions? Check all that apply.
Universal Law of Gravitation
Newton's Laws of Motion
The Law of Conservation of Energy
Hubble's Law of Cosmic Expansion
Neil is an astronaut. At the doctor's office, his weight was 180 pounds. When Neil landed on the moon, his steps were lighter and his weight was only 30 pounds. Consider this evidence and develop a claim as to why the change occurred.
Maggie found two magnets on the ground. She examined the magnets and noticed that the poles are not labeled on the magnets. She decided to hold the two ends of the magnet together to observe the forces. Based on this evidence, develop a claim about which ends of the magnets were interacting.
What happens to the magnetic force when the distance between two magnets is increased?
The force becomes stronger
The force becomes weaker
The force remains the same
Which of the following best describes the energy transformation when a ball is thrown upwards?
Potential energy is converted to thermal energy
Thermal energy is converted to kinetic energy
Potential energy is converted to kinetic energy
Kinetic energy is converted to potential energy
When a car suddenly stops, the passengers lurch forward. This is an example of which of Newton's laws?
Second Law of Motion
First Law of Motion
Law of Universal Gravitation
Third Law of Motion
