Fall Semester Final Review

Front

What is net force?

Back

The net force is the total force acting on an object after all the individual forces are combined. It determines the object's acceleration and direction.

Front

What is the definition of claim in scientific terms?

Back

A claim is a statement that asserts something to be true based on evidence or reasoning.

Front

How do you calculate momentum?

Back

Momentum (P) is calculated using the formula P = mass (m) × velocity (v).

Front

What is the law of conservation of momentum?

Back

The law states that in a closed system, the total momentum before a collision is equal to the total momentum after the collision.

Front

What type of energy does an object have when it is at rest at a height?

Back

Potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated using the formula KE = 1/2 mv².

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, conserving total mechanical energy.

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 the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).
