Forces and Motion

Front

What is speed?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is Newton's 1st Law of Motion?

Back

Newton's 1st Law states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction.

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size and opposite in direction, resulting in no net force and no change in motion.

Front

What is an unbalanced force?

Back

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

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, occurring when two surfaces come into contact.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies toward each other, depending on their masses and the distance between them.

Front

What is net force?

Back

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