10A _ Practice Motion and Newton's Law

Front

Weight is measured in grams (g) and kilogram (kg).

Back

False

Front

Weight is a force measured in newtons (N).

Back

True

Front

A 10 kg object experiences a net force of 20 Newtons. Calculate the object's acceleration.

Back

Front

What is Newton's 2nd law of motion?

Back

Front

A constant force of 12 N is applied for 3.0 s to a body initially at rest. The final velocity of the body is 6.0m s^–1. What is the mass of the body?

Back

6.0 kg

Front

An object has a mass of 30 kg and an acceleration of 2 m/s^2. What must be the net force on the object?

Back

60 N

Front

Force = mass x acceleration

Back

Law of Acceleration

Front

A boy is going down a slide. As he reaches the bottom, friction causes him to slow down and stop.

Back

Law of Inertia

Front

A book is lying at rest on a table. The book will remain there at rest because Options: there is a net force but the book has too much inertia, there are no forces acting on it at all, there is no net force on the book, there is a net force, but the book is too heavy to move

Back

there is no net force on the book

Front

If a force of 26 N is exerted on two balls, one with a mass of 0.52 kg and the other with a mass of 0.78 kg, which ball will have the greater acceleration? (F=ma)

Back

The one with a mass of 0.52 kg will have the greatest acceleration.
