Amplify: Forces & Motion 1-2

Front

What is the force that slows motion between touching objects?

Back

Friction is the force that opposes the relative motion of two surfaces in contact.

Front

Which happens first: cause or effect?

Back

Cause happens first, followed by the effect.

Front

In order for an object to speed up, in which direction must the force act?

Back

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

Front

What is the frictional force of air against a moving object called?

Back

Air Resistance is the force that opposes the motion of an object through the air.

Front

What is inertia?

Back

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

Front

What is gravity?

Back

Gravity is the force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is the relationship between force and motion?

Back

A force applied to an object can cause it to start moving, stop moving, or change direction.

Front

What is the difference between a push and a pull?

Back

A push is a force that moves an object away from you, while a pull is a force that brings an object closer to you.

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the motion of an object; it remains at rest or continues to move at a constant speed.

Front

What happens when unbalanced forces act on an object?

Back

Unbalanced forces cause an object to accelerate, changing its speed or direction.
