Forces and Newton's Laws review

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What does momentum depend on?

Back

Momentum depends on mass and velocity.

Front

What is the unit of force?

Back

Newton (N) is the unit of force.

Front

What is the formula for calculating acceleration?

Back

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

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity is approximately 9.8 m/s².

Front

What is net force?

Back

Net force is the total force acting on an object, taking into account all the individual forces.

Front

How do you calculate net force when forces are acting in opposite directions?

Back

Subtract the smaller force from the larger force and indicate the direction of the larger 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 of gravity acting on that mass.

Front

What is the formula for calculating weight?

Back

Weight = Mass x Acceleration due to gravity (W = mg).

Front

What is inertia?

Back

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