Newtons laws

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is static friction?

Back

The force that keeps an object at rest and prevents it from moving when a force is applied.

Front

What is sliding friction?

Back

The force that opposes the motion of two surfaces sliding past each other.

Front

True or False: Static friction is stronger than sliding friction.

Back

True.

Front

What is the formula for calculating weight?

Back

Weight = mass × gravity (W = m × g).

Front

If an object has a mass of 60 slugs, what is its weight on Earth?

Back

1920 pounds.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = m × a).

Front

If a car is traveling at 50 km/hr, how far does it travel in 10 seconds?

Back

139 meters.

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

True or False: Your mass would be different on the Moon than on Earth.

Back

False.
