Force and Acceleration

Front

What describes speed and direction?

Back

Velocity is the term that describes both the speed and direction of an object's motion.

Front

A free-body diagram is used to represent __________

Back

A free-body diagram is used to represent all forces acting on an object.

Front

Which of Newton's Laws of Motion states that an object in motion stays in motion unless acted on by an unbalanced force?

Back

This is known as Newton's 1st Law of Motion.

Front

__________ is an example of a non-contact force

Back

The gravitational pull on an apple is an example of a non-contact force.

Front

A measure of the amount of matter in an object

Back

Mass is the measure of the amount of matter in an object.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What is the relationship between mass and acceleration according to Newton's 2nd Law?

Back

According to Newton's 2nd Law, Force = Mass x Acceleration.

Front

What is inertia?

Back

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

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.
