Force and Motion

Front

What is the definition of force in physics?

Back

A force is a push or pull that can cause an object to accelerate, change direction, or change shape.

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 is friction?

Back

Friction is a force that opposes the motion of an object when it is in contact with another surface.

Front

What effect does increasing force have on the motion of an object?

Back

Increasing force generally results in an increase in the object's acceleration, causing it to move faster.

Front

What is motion?

Back

Motion is a change in the position of an object over time.

Front

What is the relationship between mass and force required to move an object?

Back

The greater the mass of an object, the more force is required to move it, according to Newton's second law of motion (F=ma).

Front

What is inertia?

Back

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

Front

What is the difference between a push and a pull?

Back

A push is a force that moves an object away from you, while a pull is a force that moves an object toward you.

Front

What is acceleration?

Back

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

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = m * a, where F is force, m is mass, and a is acceleration.
