Newton's Laws, Momentum and Impulse, Work and Energy Test

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 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 is the impulse-momentum theorem?

Back

The impulse-momentum theorem states that the impulse applied to an object is equal to the change in momentum of that object.

Front

How is momentum defined?

Back

Momentum is defined as the product of an object's mass and its velocity (p = mv).

Front

What happens to kinetic energy as an object rolls down an incline?

Back

As an object rolls down an incline, its potential energy is converted into kinetic energy, reaching maximum kinetic energy at the bottom.

Front

What is the formula for calculating work?

Back

Work is calculated as the product of force and displacement in the direction of the force (W = Fd).

Front

What is the relationship between work and energy?

Back

Work done on an object results in a change in its energy; specifically, work can increase or decrease an object's kinetic or 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.

Front

What is the unit of force in the SI system?

Back

The unit of force in the SI system is the Newton (N).

Front

How do you calculate the weight of an object?

Back

Weight is calculated as the mass of the object multiplied by the acceleration due to gravity (W = mg).
