Forces and Motion Concepts

Front

What is the unit of force?

Back

Newton

Front

According to Newton's Third Law, if a bug splatters against a moving car, how does the force of the bug on the car compare to the force of the car on the bug?

Back

The forces are the same.

Front

How do you find the net force when two forces are acting in the same direction?

Back

Add the forces together.

Front

What is the net force if there are 400 N forces acting downwards and no forces acting upwards?

Back

400 N Down

Front

What is the net force in the vertical direction if there are equal forces acting upwards and downwards?

Back

0 N

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m * a)

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

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 gravitational force?

Back

Gravitational force is the attraction between two masses.
