Force and Motion Review

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its motion, resulting in acceleration.

Front

What does tension refer to in physics?

Back

Tension is the pulling force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

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 are balanced forces?

Back

Balanced forces are two or more forces acting on an object that are equal in size and opposite in direction, resulting in no change in motion.

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance / Time).

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 acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur due to a change in speed or direction.

Front

What is air resistance?

Back

Air resistance is a type of friction that acts against the motion of an object moving through the air, slowing it down.

Front

What is the role of mass in motion?

Back

Mass is a measure of the amount of matter in an object, and it affects how much force is needed to change the object's motion.

Front

What is an example of an object in motion?

Back

A car driving down the road is an example of an object in motion.
