Question | Answer |
---|---|
The force that pulls objects toward each other. | Gravity |
The force of gravity on an object at the surface of the planet. | Weight |
The greatest velocity a falling object can achieve. | Terminal velocity |
The motion of a falling object when the only force acting on it is gravity. | Free Fall |
A push or a pull exerted on an object. | Force |
The overall force on an object when all the individual forces acting on an object are added together. | Net force |
The force that one surface exerts on another when the two rub against each other. | Friction |
The tendency of an object to resist any change in its motion. | Inertia |
The fluid friction experienced by objects falling through the air. | Air resistance |
A unit of measure that equals the force required to accelerate one kilogram of mass at 1 meter per second per second. | Newton |
Equal forces acting on an object in opposite directions. | Balanced forces |
A nonzero net force, which changes an object’s motion. | Unbalanced forces |
Write the mathematical formula for force. | Mass x Acceleration |
Write the mathematical formula for acceleration. | Force/Mass |
