Describing Motion
This type of energy is possessed by any object that is currently in motion.
Kinetic Energy
A type of force that moves an object away in physical science.
A Push
If you apply the same amount of force to a baseball and a heavy bowling ball, this ball will experience the greater change in motion.
The Baseball
This invisible contact force acts between two touching surfaces and works in the opposite direction of the sliding object.
Friction
Newton's First Law states that a soccer ball resting on the grass will stay completely still until it is acted up by this.
An Unbalanced Force
To fully describe an object's motion, you must state these two things: how fast it is going and where it is headed.
Speed and Direction
A type of force that brings an object closer in physical science.
A Pull
This property describes the amount of matter in an object, which determines how much it will resist a change in its motion.
Mass
This term describes the event when two or more moving objects strike each other, resulting in a transfer of energy.
Collision
Newton's Third Law states that for every action force there is an equal but opposite one of these.
If a car travels 60 miles in one hour, "60 miles per hour" is a measurement of this rate.
Speed
This is the term for the overall combination of all individual forces acting on a single object.
Net Force
To make an object with a very large mass accelerate at the same rate as an object with a small mass, you must apply this.
A Greater Force
When a moving pendulum hits a stationary ball, this basic physical quantity is transferred from one object to another.
Energy
According to Newton's Second Law, if you push a heavy grocery cart and an empty grocery cart with the exact same force, this cart will speed up much faster.
The Empty Cart
This term describes an object's location relative to a starting point or a background object.
Position
When the Net Force on a still object is exactly zero, the forces are described by this term, meaning the object won't move.
If two identical toy cars are lined up and Car A is kicked harder than Car B, Car A will experience a greater change in this.
Motion (Speed, Acceleration)
This is what happens to a rolling soccer ball's Kinetic energy as friction from the grass causes it to slow down and stop.
It transforms into Thermal energy (heat)
Newton's First Law is often called the law of this property, which is an object's natural resistance to any change in its motion.
Inertia
These four cardinal compass points describe an object's direction of travel.
North, South, East and West
This type of force is required to make a stationary object start moving or to change its speed or direction.
Unbalanced Force
True or False: An object with a huge mass requires zero force to keep moving at a constant speed in a friction-free vacuum.
True
To reduce the friction slowing down a moving object, engineers often apply this type of slippery substance.
Oil, Wax, Lubricant
When a rocket launches, the downward push of the exhaust gas is the action force while this is the reaction Force.
The upward movement of the rocket (Thrust, Acceleration)
