Unit 3 Force Total of All

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

How does mass affect acceleration?

Back

According to Newton's second law, acceleration is inversely proportional to mass. A smaller mass results in greater acceleration when the same force is applied.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion, whether at rest or in motion.

Front

What is the relationship between net force and motion?

Back

An object will remain at rest or in uniform motion unless acted upon by a net force.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = m * a, where m is mass and a is acceleration.

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

Back

The unit of force is the Newton (N).

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces result in a change in motion, causing an object to accelerate in the direction of the net force.

Front

What is the effect of friction on motion?

Back

Friction is a force that opposes motion, causing objects to slow down or stop.
