Unit 2 Energy, Motion, and Forces 21-22

Front

What is constant speed?

Back

Constant speed means that an object covers equal distances in equal intervals of time, regardless of how small those intervals are.

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the total forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

What is air resistance?

Back

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

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion of the object.

Front

What is a balanced force?

Back

A balanced force is when two forces acting on an object are equal in size but opposite in direction, causing no movement.

Front

What is a pushing force?

Back

A pushing force is a force that moves an object away from the source of the force.

Front

What is gravity?

Back

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

Front

What is motion?

Back

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

Front

What is speed?

Back

Speed is the distance traveled per unit of time, often measured in meters per second (m/s).
