KE = mv^2
KE = 1/2 mv^2
KE = Fd
KE = mgh
Answer explanation
The correct formula for kinetic energy (KE) is KE = 1/2 mv^2, where m is mass and v is velocity. This formula shows that kinetic energy is proportional to the mass and the square of the velocity.

What is the SI unit of kinetic energy?
Pascal (Pa)
Watt (W)
Joule (J)
Newton (N)
Answer explanation
The SI unit of kinetic energy is the Joule (J). It measures energy, including kinetic energy, which is the energy of motion. Other options like Pascal, Watt, and Newton represent pressure, power, and force, respectively.

What is the formula for potential energy?
PE = 1/2 mv^2
PE = mv^2
PE = Fd
PE = mgh
Answer explanation
The formula for potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height. This formula calculates the energy stored due to an object's position in a gravitational field.

What does 'g' represent in the potential energy formula?
Gravity
Velocity
Height
Mass
Answer explanation
In the potential energy formula, 'g' represents the acceleration due to gravity. It quantifies the force of gravity acting on an object, which is essential for calculating gravitational potential energy.

What is the definition of momentum?
Work done per unit time
Energy per unit time
Force times distance
Mass times velocity
Answer explanation
Momentum is defined as mass times velocity. This means that an object's momentum depends on both its mass and how fast it is moving, making 'mass times velocity' the correct choice.

What is the unit of momentum?
Kilogram meter per second (kg m/s)
Newton (N)
Joule (J)
Watt (W)
Answer explanation
Momentum is defined as the product of mass and velocity. The unit of mass is kilograms (kg) and the unit of velocity is meters per second (m/s), thus the unit of momentum is kilogram meter per second (kg m/s).

What is impulse defined as?
Force times distance
Energy times time
Force times time
Mass times velocity
Answer explanation
Impulse is defined as the product of force and the time duration over which it acts. Therefore, the correct answer is 'Force times time', which reflects how impulse relates to changes in momentum.
