Physics - Winter Break Holiday Review

Front

What is Newton's Third Law of Motion?

Back

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

Front

Explain the difference between weight and mass.

Back

Weight is the force exerted on an object due to gravity, while mass is the amount of matter in the object.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = Force (F) / Mass (m).

Front

If the force acting on an object is doubled, what happens to its acceleration?

Back

The acceleration will also double, assuming mass remains constant.

Front

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

Back

The unit of force is the Newton (N).

Front

Define mass in a physics context.

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg).

Front

What happens to the weight of an object if the gravitational force increases?

Back

The weight of the object increases, as weight is the product of mass and gravitational acceleration.

Front

What is the relationship between mass and weight?

Back

Weight = Mass × Gravitational Acceleration (W = m × g).

Front

What is an example of an object in uniform motion?

Back

A sleigh traveling at a constant speed in a straight line.

Front

What is the effect of friction on motion?

Back

Friction opposes motion, causing objects to slow down or stop.
