Forces and Newton's Laws

Front

What is constant velocity?

Back

Constant velocity refers to an object traveling at the same speed in a straight line.

Front

What does Newton's 3rd Law state?

Back

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

Front

What is tension in the context of forces?

Back

Tension is the force exerted by a rope or string when it is pulled tight.

Front

What does friction do in relation to motion?

Back

Friction always opposes the direction of motion.

Front

What is the unit of measurement for force?

Back

The unit of measurement for force is Newtons (N).

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 unless acted upon by a net external force.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = m * a, where F is force, m is mass, and a is acceleration.

Front

What is an example of balanced forces?

Back

An example of balanced forces is two people pulling on opposite ends of a rope with equal force, resulting in no movement.

Front

What is an example of unbalanced forces?

Back

An example of unbalanced forces is a car accelerating when the engine exerts more force than the friction opposing it.
