Review for 8th Science FCAT (Forces & Motion)

Front

What is friction?

Back

Friction is a type of force that resists motion between two surfaces that are pressed together.

Front

What does it mean when forces are balanced?

Back

When forces are balanced, the object is not moving, and the net force acting on it is zero.

Front

What is thrust?

Back

Thrust is a forward force that propels an object in motion.

Front

What is inertia?

Back

Inertia is the tendency of an object at rest to stay at rest unless acted upon by a force.

Front

What is net force?

Back

Net force is the overall force acting on an object after all the forces are combined.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the force that pulls objects toward the Earth.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is an unbalanced force?

Back

An unbalanced force is when the forces acting on an object are not equal, causing the object to accelerate.

Front

What is the formula for calculating net force?

Back

Net force = Force applied - Force of resistance.

Front

What is the role of air resistance?

Back

Air resistance is a force that opposes the motion of an object moving through the air.
