Newton Meter
A device used to measure the magnitude of a force.
A tool for measuring temperature.
An instrument for measuring speed.
A device for measuring distance.
Braking Distance
The distance a vehicle travels under the braking force, affected by road and weather conditions and the vehicle's condition.
The distance a vehicle travels before it starts to brake.
The distance a vehicle travels after the brakes have been applied until it comes to a complete stop.
The distance a vehicle can travel without any external forces acting on it.
Balanced Forces
A resultant force of zero.
A force that causes an object to accelerate.
A force that changes the direction of an object.
A force that is always greater than other forces.
Human Reaction Time
The time it takes for the brain to react to a stimulus, typically between 0.2-0.9 seconds.
The time it takes for the brain to process information, usually around 1-2 seconds.
The time it takes for a person to respond to a question, generally less than 0.1 seconds.
The time it takes for the body to recover from fatigue, often several minutes.
Distance-Time Graph
A plot of how an object’s distance changes over time. The gradient equals the object's speed at that point.
A representation of an object's speed over time.
A graph showing the acceleration of an object.
A chart that displays the total distance traveled by an object.
Elastic Limit
The maximum stress that a material can withstand without permanent deformation.
The point at which a material begins to fracture.
The force beyond which an object will no longer deform elastically and will deform plastically.
The ability of a material to return to its original shape after deformation.
Friction
A force that accelerates objects in motion.
A resistive contact force that acts to oppose the relative motion between two surfaces.
A force that increases the speed of an object.
A force that only acts on stationary objects.
Newton Metre
The unit of a moment.
A unit of force.
A unit of energy.
A unit of power.
Equilibrium
An object is in equilibrium if the resultant force is equal to zero.
An object is in equilibrium if it is at rest only.
An object is in equilibrium if it is moving at a constant speed.
An object is in equilibrium if the net force is greater than zero.
Acceleration
The rate of change of velocity. It can be calculated from the gradient of a velocity-time graph.
The total distance traveled divided by the total time taken.
The change in speed over a fixed distance.
The force applied to an object divided by its mass.
Hooke’s Law
The extension of a spring is inversely proportional to the force applied to it.
The extension of a spring is directly proportional to the force applied to it, up to the limit of proportionality.
The extension of a spring is independent of the force applied to it.
The extension of a spring is proportional to the square of the force applied to it.
Contact Force
A force that acts on an object through physical contact.
A force that acts at a distance without physical contact.
A force that is always in motion.
A force that can only be applied by living beings.
Distance
A measure of how far an object moves, dependent on direction, and is a vector quantity.
A measure of how far an object moves, not dependent on direction, and is a scalar quantity.
The total length of the path traveled by an object, regardless of direction, and is a scalar quantity.
The shortest path between two points, which is a vector quantity.
Elastic Deformation
A permanent change in shape that does not revert back to the original form.
A non-permanent deformation where the object returns to its original shape when forces are removed.
A type of deformation that occurs only under extreme pressure.
A deformation that occurs only in liquids and gases.
