Forces and Motion Review

Front

What is friction?

Back

Friction is the unbalanced force that opposes the motion of an object, causing it to slow down or stop.

Front

What does Newton's third law of motion state?

Back

Newton's third law of motion states that for every action force, there is an equal and opposite reaction force.

Front

How is acceleration measured?

Back

Acceleration is measured in meters per second squared (m/s²).

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that cause an object to change its motion, resulting in acceleration.

Front

What is the reaction force when a cup is placed on a table?

Back

The reaction force is the force of the table on the cup, which supports the cup's weight.

Front

What is inertia?

Back

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

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented as p = mv.

Front

What is Newton's first law of motion?

Back

Newton's first law of motion states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an unbalanced force.

Front

What is the formula for calculating force?

Back

Force is calculated using the formula F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).
