Newton's Laws of Motion Quiz

The overall force acting on an object, resulting from the difference between the applied force and the opposing force.

The force exerted by gravity on an object. It always pulls an object downwards towards the center of the Earth.

The force exerted by a surface on an object resting on it. It acts perpendicular to the surface and balances the weight of the object.

A force that opposes the motion of an object, acting in the opposite direction of the applied force.

The force applied to move an object.

The difference between the applied force and the frictional force. It determines the overall direction and magnitude of the object's motion.

A simple visual representation of all the forces acting on an object.

The tendency of an object to resist changes in its motion.

A force that acts to change an object's state of motion, either at rest or in motion, when left unopposed. It is the push or pull that causes an object to accelerate.

A scalar quantity representing an object's resistance to acceleration. It's measured in kilograms (kg).

A state of motion where an object is not accelerating (either at rest or moving at a constant speed). This happens when all forces acting on the object are balanced.

Forces acting on an object are considered unbalanced when they cause the object to accelerate, meaning its speed or direction changes.

A force that opposes motion between two surfaces in contact. It acts in the opposite direction of the applied force.

The force exerted by the Earth on any object with mass. It's always directed towards the center of the Earth.

Newton's Second Law describes how objects behave when the forces acting on them are unbalanced. It explains that forces don't create motion directly, but rather cause changes in motion, known as acceleration.

Newton's Second Law states that the net force acting on an object is directly proportional to the object's mass and the acceleration it experiences.

Acceleration is the rate of change of velocity, meaning how fast the object's speed or direction changes over time.

The net force is the sum of all forces acting on an object. It determines the object's overall motion.

Friction is a force that opposes motion between surfaces in contact, resisting movement.

The net force is equal to the sum of all forces acting on an object. It determines the overall motion of the object. This formula is used for objects in motion along a horizontal surface.

Friction acts in the opposite direction of motion, so its value is negative when calculating the net force.

The coefficient of friction (µ) represents the ratio of friction to the normal force between two surfaces. It indicates how much friction exists between two surfaces.

Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. This law helps to explain the relationship between normal force and weight.

The Law of Interaction describes how forces between objects cause movement, like a fish pushing water with its tail to propel itself forward.

Static friction is the force that must be overcome to start an object moving. It's like the resistance you feel when pushing a heavy box from rest.

Kinetic friction is the force that acts between surfaces in contact when they are moving relative to each other. It's like the resistance you feel when sliding a box across the floor.

Applied force is the force directly applied to an object to make it move. It's like the force you use when pushing a door open.

Normal force is the force that acts perpendicular to a surface, supporting an object's weight. It's like the force the ground exerts on your feet when you stand.

Weight is the force of gravity acting on an object's mass. It's like the force pulling you down towards the Earth.

A force pair is two forces that act on different objects and are equal in magnitude but opposite in direction. It's like the fish pushing the water and the water pushing back on the fish.

A change in an object's velocity, which can involve changing speed, direction, or both.
