Force & Motion Unit Exam-Mod

Front

What is force?

Back

A force is a push or pull that can cause an object to accelerate, change direction, or change shape.

Front

What is motion?

Back

Motion is the change in position of an object over 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 air resistance?

Back

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

Front

What is inertia?

Back

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

Front

What are balanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in an object's motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are not equal and can cause an object to accelerate in the direction of the greater force.

Front

What is net force?

Back

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

Front

How do you calculate net force?

Back

Net force can be calculated by adding all the forces acting on an object, taking into account their direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can be caused by a change in speed or direction.
