Physics Midterm Review 2024

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What does Newton's 2nd Law state?

Back

Newton's 2nd Law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma).

Front

What type of friction does a feather experience while falling?

Back

A feather experiences fluid friction as it moves through the air.

Front

In which direction does friction act?

Back

Friction acts in the opposite direction of movement.

Front

What is work in physics?

Back

Work is done when a force is applied to an object and the object moves a distance in the direction of the force.

Front

What is the formula for calculating work?

Back

Work = Force x Distance.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as gravitational potential energy.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
