Physical Science Semester 1 Review

Front

What is the force exerted by the surface an object is resting on?

Back

Force normal.

Front

How do you calculate the time taken to travel a distance at a constant speed?

Back

Time = Distance / Speed.

Front

What happens to energy when a baseball falls from its highest point?

Back

The energy changes from potential to kinetic.

Front

What is the formula to calculate force?

Back

Force = Mass x Acceleration.

Front

How does kinetic energy change with speed?

Back

Kinetic energy is proportional to the square of the speed.

Front

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

Back

Newton (N).

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

Acceleration is directly proportional to force and inversely proportional to mass.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy = 0.5 x Mass x Velocity^2.

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is energy of motion.

Front

What is the effect of friction on motion?

Back

Friction opposes motion and can cause objects to slow down or stop.
