Force & Motion

What is force?

• Force is the weight of an object.
• Force is an interaction that changes the motion of an object.
• Force is a type of energy.
• Force is the speed of an object.

What is net force?

• Net force is the total force acting on an object, taking into account all individual forces.
• Net force is the force that opposes motion without considering other forces.
• Net force is the sum of all forces acting in the same direction only.
• Net force is the force applied by a single object only.

What is balanced forces?

• Balanced forces are forces that are equal in magnitude and opposite in direction, leading to a net force of zero.
• Balanced forces are unequal forces acting in the same direction.
• Balanced forces are forces that cause an object to accelerate.
• Balanced forces are forces that result in a net force greater than zero.

What is unbalanced forces?

• Unbalanced forces are always equal in magnitude.
• Unbalanced forces do not affect the motion of an object.
• Unbalanced forces are only present in static situations.
• Unbalanced forces are forces that cause an object to change its state of motion. When force applied is greater than the force applied opposite direction.

What is friction?

• Friction is the energy lost when two surfaces are separated.
• Friction is the force that enhances the motion of two surfaces in contact.
• Friction is the force that opposes the relative motion of two surfaces in contact.
• Friction is the temperature increase caused by two surfaces rubbing together.

What is inertia?

• Inertia is the force that causes an object to move.
• Inertia is the speed of an object in motion.
• Inertia is the energy stored in an object at rest.
• Inertia is the inherent property that make it opposed would cause a change in its motion.

What is the definition of motion?

• Motion is the force applied to an object.
• Motion is the change in position of an object over time.
• Motion is the speed of an object at rest.
• Motion is the color of an object in space.

What is definition of Newton's First Law?

• An object will accelerate unless a force is applied.
• An object will remain at rest or in uniform motion unless acted upon by a net external force.
• An object will change direction only if a force is applied.
• An object will remain in motion only if it is in a vacuum.

What is definition of Newton's Second Law?

• Newton's Second Law states that energy is conserved in a closed system.
• Newton's Second Law describes the motion of objects in a vacuum.
• Newton's Second Law defines the relationship between force, mass, and acceleration, expressed as F = ma.
• Newton's Second Law relates pressure and volume in gases.

What is the definition mass?

• Mass is the volume of an object.
• Mass is the speed of an object.
• Mass is the amount of matter in an object.
• Mass is the weight of an object.
