Potential Energy
This is the general term for the energy an object has stored due to its position, shape, or configuration.
What is potential energy?
This is the general definition of kinetic energy.
What is the energy of motion?
The tendency of an object to resist changes in its state of motion
What is inertia?
This term describes a push or pull that can change an object's motion.
What is force?
This law of motion states that for every action, there is an equal and opposite reaction.
Newton's Third Law of Motion
True or false: a ball on the ground has more potential energy than a ball on a hill.
What is false?
True or false: bowling uses kinetic energy.
What is true?
This is the specific physical property of an object that determines how much inertia it has.
What is mass?
According to Newton's Second Law of Motion, acceleration depends on two factors: net force and this other quantity.
What is mass?
If the action force is a person pushing down on a chair, the reaction force is the chair pushing back on the person in this direction.
upward on the person
The energy stored in a stretched rubber band or a compressed spring is an example of this specific type of potential energy.
What is elastic potential energy?
While both mass and speed affect kinetic energy, this factor has a greater impact because it is squared in the calculation.
What is speed (or velocity)?
When a moving car suddenly brakes, passengers continue to move forward, a phenomenon that provides a common example of this law of motion.
What is Newton's First Law of Motion
A force of 25 Newtons acts upon a 5 kilogram object. This is the resulting acceleration in meters per second squared.
What is 5 m/s²
When a swimmer pushes water backward, the reaction force from the water pushes the swimmer in this direction.
forward
The energy stored within the chemical bonds of substances like food, fuel, and batteries is known as this type of potential energy.
What is chemical potential energy?
The standard unit of measurement for kinetic energy, which is the same unit used for work.
What is the Joule
The car with the greatest amount of this property, say a large truck versus a small car, will require more force to stop when moving at the same speed.
What is inertia (or mass
This is the name of the law which states that an object in motion will stay in motion, and an object at rest will stay at rest, unless acted upon by an unbalanced force.
What is Newton's First Law of Motion (or the Law of Inertia)?
A large hammer hits a small nail. According to Newton's third law, the force on the hammer and the force on the nail are this in magnitude.
equal in magnitude but opposite in direction
A 15 kg boulder resting at the top of a 12-meter cliff has this many Joules of gravitational potential energy using g =9.8 m/s to the second power
What is 1764 Joules?
True or false: watching TV uses kinetic energy.
What is False?
This scientist first formulated the concept of the law of inertia, later generalized by Isaac Newton.
Who is Galileo Galilei?
You pull on a box with a force of 10 N to the right, while a friend pulls with 4 N to the left. The magnitude and direction of the net force on the box is this.
What is 6 N to the right?
The action-reaction pair that allows you to walk involves your feet pushing backward on the ground and the ground pushing you in this direction.
