What is the SI unit of force?
Joule (J)
Pascal (Pa)
Newton (N)
Watt (W)
What is the formula to calculate acceleration?
acceleration = final velocity / time
acceleration = (final velocity * initial velocity) / time
acceleration = (final velocity - initial velocity) / time
acceleration = (final velocity + initial velocity) / time
Explain the concept of Newton's First Law of Motion.
Objects in motion will stop without any external force
An object will accelerate when no force is applied
Newton's First Law states that objects will always move in a circular path
An object will stay still or keep moving at a constant velocity unless a net external force acts upon it.
Define the term 'work' in physics.
Work is measured in kilograms.
Work is the same as power.
Work is the result of speed and time.
Work is the product of force and distance.
What is the law of conservation of energy?
Energy can be transformed into matter
Energy can be destroyed completely
Energy can be created out of nothing
Energy cannot be created or destroyed, only transferred or transformed.
Describe the difference between mass and weight.
Mass is a measure of the amount of matter in an object, while weight is the force of gravity acting on that mass.
Mass is measured in pounds, while weight is measured in kilograms.
Mass is a scalar quantity, while weight is a vector quantity.
Mass is a measure of volume, while weight is a measure of density.
What is the formula to calculate momentum?
p = m * v
p = m / v
p = m + v
p = m ^ v
Explain the concept of centripetal force.
Centripetal force is the force that causes an object to move in a straight line.
Centripetal force is the force that pushes an object away from the center of rotation.
Centripetal force is the force that increases an object's speed in a circular path.
Centripetal force is the force that keeps an object moving in a circular path.
Define the term 'power' in physics.
Power is the speed of an object in motion.
Power is the ability to lift heavy objects.
Power is the force exerted by an object.
Power in physics is the rate at which work is done or energy is transferred. It is measured in watts (W) and is calculated as the product of force and velocity.
What is the relationship between frequency and wavelength in physics?
Direct
Inverse
Parallel
Unrelated
