Amplify- Force and Motion Chapter 1

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction of the object's movement.

Front

What happens to an object when friction acts on it?

Back

Friction slows down the object, reducing its speed.

Front

Is there friction on Earth?

Back

Yes, there is friction on Earth; it is a common force that affects the motion of objects.

Front

What is the relationship between force and motion?

Back

A stronger force will cause an object to accelerate faster than a weaker force.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What must happen for an object to stop moving?

Back

A force must act in the opposite direction of the object's motion.

Front

What direction must a force act to speed up an object?

Back

The force must act in the same direction as the object's motion.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

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 at a constant velocity unless acted upon by a net external force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
