Front

What is net force?

Back

The net force is the total amount of force acting on an object, taking into account both the magnitude and direction of all individual forces.

Front

What happens when two identical sheets of paper are dropped from the same height, one crumpled and one flat?

Back

The crumpled sheet will fall faster due to reduced air resistance compared to the flat sheet.

Front

Where is the most potential energy located in a roller coaster model?

Back

The most potential energy is located at the highest point of the roller coaster.

Front

True or False: Any amount of force can cause an object to bend, but a specific amount of force is needed for an object to reach its breaking point.

Back

True.

Front

Which factor has the most impact on kinetic energy?

Back

Velocity has the most impact on kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses 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, often associated with height in a gravitational field.

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

Front

What is air resistance?

Back

Air resistance is a type of friction that acts against the motion of an object moving through air, affecting its speed and acceleration.

Front

What is the breaking point of a material?

Back

The breaking point is the specific amount of force or stress that a material can withstand before it fails or breaks.
