What is Newton's First Law of Motion?
An object will change direction only when a force is applied.
An object will accelerate unless a force is applied.
An object will remain at rest or in uniform motion unless acted upon by an external force.
An object in motion will eventually stop without any force.
Which law states that force equals mass times acceleration?
Newton's Third Law of Motion
Newton's First Law of Motion
Newton's Second Law of Motion
Law of Universal Gravitation
What is the unit of force in the International System of Units?
watt (W)
pascal (Pa)
newton (N)
joule (J)
If an object is at rest, what will cause it to move?
The object will start moving if it is observed.
A net external force applied to the object.
Gravity will pull the object into motion.
The object will move on its own over time.
What is the relationship between mass and weight?
Weight is independent of gravity.
Weight is the force due to gravity acting on mass.
Weight is the same as mass.
Mass is the force acting on weight.
How do you calculate the net force acting on an object?
Net force is the vector sum of all individual forces acting on an object.
Net force is the difference between the largest and smallest forces.
Net force is the average of all forces acting on the object.
Net force is the total mass of the object.
What does the term 'inertia' refer to?
Inertia is the resistance of an object to any change in its motion.
Inertia refers to the speed of an object in motion.
Inertia is the energy stored in an object at rest.
Inertia is the force that causes an object to move faster.
What is the effect of friction on motion?
Friction enhances motion and speeds up moving objects.
Friction has no effect on motion whatsoever.
Friction only affects stationary objects and not those in motion.
Friction opposes motion and can slow down or stop moving objects.
How is speed different from velocity?
Speed is a scalar quantity; velocity is a vector quantity that includes direction.
Speed and velocity are interchangeable terms with no differences.
Speed measures distance over time; velocity measures speed only.
Speed is a vector quantity; velocity is a scalar quantity.
What is the significance of the gravitational constant?
It is used to calculate the mass of an object.
It defines the shape of the universe.
It measures the speed of light in a vacuum.
The gravitational constant is significant because it determines the strength of gravitational interactions between masses.
What is the purpose of measurements in physics?
To confuse scientists
To ignore physical laws
The purpose of measurements in physics is to quantify physical properties and phenomena.
To create theories without data
How do you convert between different units of measurement?
Use conversion factors to multiply or divide the value to convert between units.
Use a calculator to find the average of the units.
Ignore the units and just use the numbers as they are.
Add the units together to get a new unit.
