In a frictionless environment with no air resistance or gravity, what happens to an object once it is given a velocity?

• It continues moving at the same velocity.

• It stops immediately.

• It accelerates indefinitely.

• It slows down gradually.

Who was the first person to claim that an object in motion stays in motion unless acted upon by an external force?

• Albert Einstein

• Galileo Galilei

• Isaac Newton

• Nikola Tesla

According to Newton's second law, what is the relationship between force, mass, and acceleration?

• F = m + a

• F = m / a

• F = m * a

• F = a / m

• It doubles.

• It halves.

• It quadruples.

What is the difference between mass and weight?

• Mass changes with location, weight does not.

• Weight is the force of gravity on an object, mass is the amount of matter in an object.

• Mass is measured in Newtons, weight in kilograms.

• Weight is constant, mass changes with gravity.

What is the force of gravity on a 10 kg mass on Earth's surface?

• 9.8 Newtons

• 98 Newtons

• 100 Newtons

• 10 Newtons

According to Newton's third law, what happens when you push on an object?

• The object accelerates indefinitely.

• The object moves in the direction of the push.

• The object pushes back with an equal and opposite force.

• The object does not move.

Why can you walk forward according to Newton's third law?

• Because of air resistance.

• Because the ground pushes forward on your shoes.

• Because of gravity.

• Because of friction.
