Motion, Force, Energy and Work for Physical Science

Front

What is the equation to calculate speed?

Back

speed = distance/time

Front

What are the units for energy?

Back

Joules (J)

Front

Calculate the potential energy of a rock with a mass of 55 kg while sitting on a hill that is 35 m high.

Back

18,865 J

Front

How much kinetic energy does a 0.145 kg baseball thrown at a velocity of 30.0 m/s have?

Back

65.25 J

Front

What does the strength of gravity between two objects depend upon?

Back

Mass & distance

Front

Define force in the context of physical science.

Back

Force is an interaction that causes an object to change its velocity, measured in Newtons (N).

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is work in physics?

Back

Work is done when a force causes an object to move, calculated as Work = Force x Distance.

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is the energy of motion.
